±15kV ESD Protected, 3.3V, Full Fail-Safe, Low Power, High Speed or Slew Rate
Limited, RS-485/RS-422 Transceivers
DATASHEET
The Intersil ISL317xE are ±15kV IEC61000 ESD protected,
3.3V powered single transceivers that meet both the RS-485
and RS-422 standards for balanced communication. These
devices have very low bus currents (+125mA/-100mA), so
they present a true “1/8 unit load” to the RS-485 bus. This
allows up to 256 transceivers on the network without
violating the RS-485 specification’s 32 unit load maximum,
and without using repeaters. For example, in a remote utility
meter reading system, individual meter readings are routed to
a concentrator using an RS-485 network, so the high allowed
node count minimizes the number of repeaters required.
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which
ensures a logic high Rx output if Rx inputs are floating,
shorted, or terminated but undriven.
Hot Plug circuitry ensures that the Tx and Rx outputs remain
in a high impedance state while the power supply stabilizes.
The ISL3170E through ISL3175E utilize slew rate limited
drivers which reduce EMI, and minimize reflections from
improperly terminated transmission lines, or unterminated
stubs in multidrop and multipoint applications. Slew rate
limited versions also include receiver input filtering to
enhance noise immunity in the presence of slow input signals.
The ISL3170E, ISL3171E, ISL3173E, ISL3174E, ISL3176E,
and ISL3177E are configured for full duplex (separate Rx
input and Tx output pins) applications. The half duplex
versions multiplex the Rx inputs and Tx outputs to allow
transceivers with output disable functions in 8 Ld packages.

Pin Descriptions
PIN FUNCTION
RO Receiver output: If A-B ≥ -50mV, RO is high; If A-B ≤ -200mV, RO is low; if A and B are unconnected (floating) or shorted, RO = High.
RE Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. If the Rx enable function is not required,
connect RE directly to GND or through a 1kΩ to 3kΩ resistor to GND.
DE Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high, and are high impedance when DE is low. If the Tx enable
function is not required, connect DE to VCC through a 1kΩ to 3kΩ resistor.
DI Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low.
GND Ground connection.
A/Y ±15kV IEC61000 ESD Protected RS-485/422 level, noninverting receiver input and noninverting driver output. Pin is an input if DE = 0; pin
is an output if DE = 1.
B/Z ±15kV IEC61000 ESD Protected RS-485/422 level, Inverting receiver input and inverting driver output. Pin is an input if DE = 0; pin is an
output if DE = 1.
A ±15kV IEC61000 ESD Protected RS-485/422 level, noninverting receiver input.
B ±15kV IEC61000 ESD Protected RS-485/422 level, inverting receiver input.
Y ±15kV IEC61000 ESD Protected RS-485/422 level, noninverting driver output.
Z ±15kV IEC61000 ESD Protected RS-485/422 level, inverting driver output.
VCC System power supply input (3.0V to 3.6V).

NOTES:
6. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless
otherwise specified.
7. Supply current specification is valid for loaded drivers when DE = 0V.
8. Applies to peak current. See “Typical Performance Curves” starting on page 14 for more information.
9. When testing devices with the shutdown feature, keep RE = 0 to prevent the device from entering SHDN.
10. When testing devices with the shutdown feature, the RE signal high time must be short enough (typically <100ns) to prevent the device from
entering SHDN.
11. Versions with a shutdown feature are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the
parts are ensured not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are ensured to have entered shutdown. See
“Low Power Shutdown Mode” on page 13.
12. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
13. Set the RE signal high time >600ns to ensure that the device enters SHDN.
14. Does not apply to the ISL3171E, ISL3174E, or ISL3177E.
15. tSKEW is the magnitude of the difference in propagation delays of the specified terminals of two units tested with identical test conditions (VCC,
temperature, etc.). Applies only to the ISL3176E through ISL3178E.
16. ISL3170E through ISL3175E only.
17. VCC ≥ 3.15V.
18. Limits established by characterization and are not production tested.
19. If the Tx or Rx enable function is not needed, connect the enable pin to the appropriate supply (see “Pin Descriptions” on page 4) through a 1kΩ
to 3kΩ resistor.
20. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
21. If the DE or RE input voltage exceeds the VCC voltage by more than 500mV, then current will flow into the logic pin. The current is limited by a
340Ω resistor (so ≈ 13mA with VIN = 5V and VCC = 0V) so no damage will occur if VCC ≤ VIN ≤ 7V for short periods of time.
Electrical Specifications Test Conditions: VCC = 3.0V to 3.6V; unless otherwise specified. Typicals are at VCC = 3.3V, TA = +25°C,

Application Information
RS-485 and RS-422 are differential (balanced) data
transmission standards for use in long haul or noisy
environments. RS-422 is a subset of RS-485, so RS-485
transceivers are also RS-422 compliant. RS-422 is a
point-to-multipoint (multidrop) standard, which allows only
one driver and up to 10 receivers on each bus, assuming
one unit load devices.. RS-485 is a true multipoint standard,
which allows up to 32 one-unit load devices (any
combination of drivers and receivers) on each bus. To allow
for multipoint operation, the RS-485 specification requires
that drivers must handle bus contention without sustaining
any damage.
Another important advantage of RS-485 is the extended
common-mode range (CMR), which specifies that the driver
outputs and receiver inputs withstand signals that range from
+12V to -7V. RS-422 and RS-485 are intended for runs as
long as 4000ft, so the wide CMR is necessary to handle
ground potential differences, as well as voltages induced in
the cable by external fields.
Receiver Featu r es
These devices utilize a differential input receiver for maximum
noise immunity and common mode rejection. Input sensitivity
is better than ±200mV, as required by the RS-422 and RS-485
specifications.
Receiver input resistance of 96kΩ surpasses the RS-422
specification of 4kΩ and is eight times the RS-485 “Unit Load
(UL)” requirement of 12kΩ minimum. Thus, these products
are known as “one-eighth UL” transceivers and there can be
up to 256 of these devices on a network while still complying
with the RS-485 loading specification.
Receiver inputs function with common-mode voltages as
great as +9V/-7V outside the power supplies (that is, +12V
and -7V), making them ideal for long networks where induced
voltages and ground potential differences are realistic
concerns.
All the receivers include a “Full Fail-Safe” function that
guarantees a high level receiver output if the receiver inputs
are unconnected (floating) or shorted. Fail-safe with shorted
inputs is achieved by setting the Rx upper switching point to
-50mV, thereby ensuring that the Rx sees 0V differential as a
high input level.
Receivers easily meet the data rates supported by the
corresponding driver, and all receiver outputs (except on the
ISL3171E, ISL3174E, and ISL3177E) are tri-statable using
the active low RE input.
Driver Features
The RS-485/422 driver is a differential output device that
delivers at least 1.5V across a 54Ω load (RS-485) and at
least 2V across a 100Ω load (RS-422). The drivers feature
low propagation delay skew to maximize bit width and to
minimize EMI.
All drivers are tri-statable through the active high DE input,
except on the ISL3171E, ISL3174E, and ISL3177E.
The 250kbps and 500kbps driver outputs are slew rate
limited to minimize EMI and to reduce reflections in
unterminated or improperly terminated networks. Outputs of
the ISL3176E through ISL3178E drivers are not limited, so
faster output transition times allow data rates of at least
20Mbps.
Hot Plug Function
When a piece of equipment powers up, a period of time
occurs in which the processor or ASIC driving the RS-485
control lines (DE, RE) is unable to ensure that the RS-485
Tx and Rx outputs are kept disabled. If the equipment is
connected to the bus, a driver activating prematurely during
power up may crash the bus. To avoid this scenario, the
ISL317XE versions with output enable pins incorporate a
“Hot Plug” function. During power up, circuitry monitoring VCC
ensures that the Tx and Rx outputs remain disabled for a period
of time, regardless of the state of DE and RE. This gives the
processor/ASIC a chance to stabilize and drive the RS-485
control lines to the proper states.
ESD Protection
All pins on these devices include Class 3 (>7kV) Human
Body Model (HBM) ESD protection structures, but the
RS-485 pins (driver outputs and receiver inputs)
incorporate advanced structures allowing them to survive
ESD events in excess of ±15kV HBM and ±15kV
IEC61000. The RS-485 pins are particularly vulnerable to
ESD damage because they typically connect to an exposed
port on the exterior of the finished product. Simply touching
the port pins, or connecting a cable, can cause an ESD
event that might destroy unprotected ICs. These new ESD
structures protect the device whether or not it is powered
up, and without degrading the RS-485 common mode
range of -7V to +12V. This built-in ESD protection
eliminates the need for board level protection structures
(for example, transient suppression diodes), and the
associated, undesirable capacitive load they present.
IEC61000-4-2 Testing
The IEC61000 test method applies to finished equipment,
rather than to an individual IC. Therefore, the pins most likely
to suffer an ESD event are those that are exposed to the
outside world (the RS-485 pins in this case), and the IC is
tested in its typical application configuration (power applied)
rather than testing each pin-to-pin combination. The lower
current limiting resistor coupled with the larger charge
storage capacitor yields a test that is much more severe than
the HBM test. The extra ESD protection built into this
device’s RS-485 pins allows the design of equipment
meeting Level 4 criteria without the need for additional board
level protection on the RS-485 port.

AIR-GAP DISCHARGE TEST METHOD
For this test method, a charged probe tip moves toward the
IC pin until the voltage arcs to it. The current waveform
delivered to the IC pin depends on approach speed,
humidity, temperature, etc., so it is difficult to obtain
repeatable results. The ISL317XE RS-485 pins withstand
±15kV air-gap discharges.
CONTACT DISCHARGE TEST METHOD
During the contact discharge test, the probe contacts the
tested pin before the probe tip is energized, thereby
eliminating the variables associated with the air-gap
discharge. The result is a more repeatable and predictable
test, but equipment limits prevent testing devices at voltages
higher than ±8kV. The ISL317XE survive ±8kV contact
discharges on the RS-485 pins.
Data Rate, Cables, and Terminations
RS-485/422 are intended for network lengths up to 4000ft,
but the maximum system data rate decreases as the
transmission length increases. Devices operating at 20Mbps
are limited to lengths less than 100ft, while the 250kbps
versions can operate at full data rates with lengths of several
thousand feet.
Twisted pair is the cable of choice for RS-485/422 networks.
Twisted pair cables tend to pick up noise and other
electromagnetically induced voltages as common mode
signals, which are effectively rejected by the differential
receivers in these ICs.
Proper termination is imperative when using the 20Mbps
devices to minimize reflections. Short networks using the
250kbps versions do not need to be terminated, but
terminations are recommended unless power dissipation is
an overriding concern.
In point-to-point, or point-to-multipoint (single driver on bus)
networks, the main cable should be terminated in its
characteristic impedance (typically 120Ω) at the end farthest
from the driver. In multi-receiver applications, keep stubs
connecting receivers to the main cable as short as possible.
Multipoint (multi-driver) systems require that the main cable
be terminated in its characteristic impedance at both ends.
Keep stubs connecting a transceiver to the main cable as
short as possible.
Built-In Driver Overload Protection
As stated previously, the RS-485 spec requires that drivers
survive worst case bus contentions undamaged. These
devices meet this requirement via driver output short circuit
current limits, and on-chip thermal shutdown circuitry.
The driver output stages incorporate short circuit current
limiting circuitry which ensures that the output current never
exceeds the RS-485 spec, even at the common-mode
voltage range extremes. Additionally, these devices utilize a
foldback circuit which reduces the short circuit current, and
thus the power dissipation, whenever the contending voltage
exceeds either supply.
In the event of a major short circuit condition, devices use a
thermal shutdown feature that disables the drivers whenever
the die temperature becomes excessive. This eliminates the
power dissipation, allowing the die to cool. The drivers
automatically re-enable after the die temperature drops about
15°. If the contention persists, the thermal shutdown/re-enable
cycle repeats until the fault is cleared. Receivers stay
operational during thermal shutdown.
Low Power Shutdown Mode
These CMOS transceivers all use a fraction of the power
required by their bipolar counterparts, but some also include
a shutdown feature that reduces the already low quiescent
ICC to a 10nA trickle. These devices enter shutdown
whenever the receiver and driver are simultaneously
disabled (RE =V
CC and DE = GND) for a period of at least
600ns. Disabling both the driver and the receiver for less
than 50ns guarantees that the transceiver will not enter
shutdown.
Note that receiver and driver enable times increase when the
transceiver enables from shutdown. Refer to Notes 9 through
13 at the end of the “Electrical Specifications table” on page 9,
for more information.
