Description
-channel high-speed digital isolators
are CMOS devices manufactured with NVE’s patented* IsoLoop
®
spintronic Giant Magnetoresistive (GMR) technology.
A unique ceramic/polymer composite barrier provides excellent isolation
and virtually unlimited barrier life.
All transmit and receive channels operate at 110 Mbps over the full
temperature and supply voltage range. The symmetric magnetic coupling
barrier provides a typical propagation delay of only 10 ns and a pulse width
distortion of 2 ns, achieving the best specifications of any isolator.
Typical transient immunity of 50 kV/µs is unsurpassed. High channel
density makes these devices ideal for isolating ADCs and DACs, parallel
buses and peripheral interfaces.
The IL715, IL716, and IL717 are available in 16-pin 0.3" and 0.15" SOIC,
and ultraminiature QSOP packages.
Performance is specified over a temperature range of −40 °C to +100 °C.
“T” and “V” Series parts have a maximum operating temperature of 125 °C.
V-Series versions have an extremely high isolation voltage of 6 kV
RMS
.

Notes (apply to both 3.3 V and 5 V specifications):
1. Absolute maximum ambient operating temperature means the device will not be damaged if operated under these conditions. It does not
guarantee performance.
2. PWD is defined as |t
PHL
− t
PLH
|. %PWD is equal to PWD divided by pulse width.
3. t
PSK
is the magnitude of the worst-case difference in t
PHL
and/or t

between devices at 25°C.
4. CM

is the maximum common mode voltage slew rate that can be sustained while maintaining V
O

DD
2
. CM
L
is the maximum
common mode input voltage that can be sustained while maintaining V
O
< 0.8 V. The common mode voltage slew rates apply to both rising
and falling common mode voltage edges.
5. Device is considered a two terminal device: pins 1–8 shorted and pins 9–16 shorted.
6. Dynamic power consumption is calculated per channel and is supplied by the channel’s input side power supply.
7. Minimum pulse width is the minimum value at which specified PWD is guaranteed.
8. The relevant test and measurement methods are given in the Electromagnetic Compatibility section on p. 10.
9.
External magnetic field immunity is improved by this factor if the field direction is “end-to-end” rather than to “pin-to-pin” (see diagram on p. 10).

Figure 4. IL715/IL716/IL717 equivalent circuit (each channel).
Isolator Signal Path
The GMR isolator signal path starts with a buffered input signal that is driven through an ultraminiature coil. This generates a small magnetic
field that changes the electron spin polarization of GMR resistors, which are configured as a Wheatstone bridge. The change in spin polarization
of the resistors creates a bridge voltage which drives an output comparator to construct an isolated version of the input signal.
Small Size, High Speed, and Low EMI
The coil, GMR, and circuitry are integrated to allow small packages. GMR is inherently high speed and low distortion, and unlike transformers,
does not rely on energy transfer, so power is low and EMI emissions are minimal.
High Magnetic Immunity
GMR provides large signals which improve magnetic immunity, and the Wheatstone bridge configuration cancels ambient common-mode
magnetic fields, further enhancing immunity to external magnetic fields.

Electrostatic Discharge Sensitivity
This product has been tested for electrostatic sensitivity to the
limits stated in the specifications. However, NVE recommends that
all integrated circuits be handled with appropriate care to avoid
damage. Damage caused by inappropriate handling or storage could
range from performance degradation to complete failure.
Electromagnetic Compatibility
IsoLoop Isolators have the lowest EMC footprint of any isolation
technology. IsoLoop Isolators’ Wheatstone bridge configuration
and differential magnetic field signaling ensure excellent EMC
performance against all relevant standards.
These isolators are fully compliant with IEC 61000-6-1 and
IEC 61000-6-2 standards for immunity, and IEC 61000-6-3,
IEC 61000-6-4, CISPR, and FCC Class A standards for emissions.
Immunity to external magnetic fields is even higher if the field
direction is “end-to-end” rather than to “pin-to-pin” as shown in the
diagram below:
Cross-axis Field Direction
Dynamic Power Consumption
IsoLoop Isolators achieve their low power consumption from the
way they transmit data across the isolation barrier. By detecting the
edge transitions of the input logic signal and converting these to
narrow current pulses, a magnetic field is created around the GMR
Wheatstone bridge. Depending on the direction of the magnetic
field, the bridge causes the output comparator to switch following
the input logic signal. Since the current pulses are narrow, about
2.5 ns, the power consumption is independent of mark-to-space
ratio and solely dependent on frequency. This has obvious
advantages over optocouplers, which have power consumption
heavily dependent on mark-to-space ratio.
Thermal Management
IsoLoop Isolators are designed for low power dissipation and
thermal performance, providing unmatched channel density for
high-performance isolators. Nevertheless, package temperature rise
should be considered when running multiple channels at high
speed. Power consumption is higher at 5 volt operation than at
3.3 volts, and dynamic supply current is higher on the input side of
the isolators than the output side, so thermal management is more
important with five-volt input-side power supplies.
Based on the specifications contained in this datasheet, the derating
curve at typical operating conditions is as follows:
Standard-grade parts have a maximum junction temperature of 110°C.
T-Series parts have a maximum operating junction temperature of
125°C for additional margin at extreme operating conditions.
Power Supply Decoupling
Both power supplies should be decoupled with 0.1 µF typical
(0.047 µF minimum) capacitors as close as possible to the V
DD
pins. Ground planes for both GND
1
and GND
2
are highly
recommended for data rates above 10 Mbps.
Maintaining Creepage
Creepage distances are often critical in isolated circuits. In addition
to meeting JEDEC standards, NVE isolator packages have unique
creepage specifications. Standard pad libraries often extend under
the package, compromising creepage and clearance. Similarly,
ground planes, if used, should be spaced to avoid compromising
clearance. Package drawings and recommended pad layouts are
included in this datasheet.
Signal Status on Start-up and Shut Down
To minimize power dissipation, input signals are differentiated and
then latched on the output side of the isolation barrier to reconstruct
the signal. This could result in an ambiguous output state
depending on power up, shutdown and power loss sequencing.
Therefore, the designer should consider including an initialization
signal in the start-up circuit. Initialization consists of toggling the
input either high then low, or low then high.

This circuit illustrates a typical single-channel delta-sigma ADC. The A/D is located on the bridge with no signal conditioning electronics
between the bridge sensor and the ADC. In this case, the IL717 is the best choice for isolation. It isolates the control bus from the
microcontroller. The system clock is located on the isolated side of the system.
