General Description
The MAX4614/MAX4615/MAX4616 quad, low-voltage,
high-speed, single-pole/single-throw (SPST) analog
switches are pin compatible with the industry-standard
74HC4066/MAX4610 analog switches. On-resistance
(10Ωmax) is matched between switches to 1Ωmax
and is flat (1Ωmax) over the specified signal range.
Each switch handles V+ to GND analog signal levels.
Maximum off-leakage current is only 1nA at TA= +25°C
and 6nA at TA= +85°C.
The MAX4614 has four normally open (NO) switches,
and the MAX4615 has four normally closed (NC)
switches. The MAX4616 has two NO switches and two
NC switches. These CMOS switches operate from a
single +2V to +5.5V supply. All digital inputs have
+0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-
logic compatibility when using a single +5V supply.

Applications Information
Power-Supply Sequencing and
Overvoltage Protection
Do not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause perma-
nent damage to the devices.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals or logic inputs, especially if the analog
or logic signals are not current limited. If this sequenc-
ing is not possible, and if the analog or logic inputs are
not current limited to 20mA, add a small-signal diode
(D1) as shown in Figure 1. If the analog signal can dip
below GND, add D2. Adding protection diodes
reduces the analog signal range to a diode drop (about
0.7V) below V+ (for D1), and to a diode drop above
ground (for D2). Leakage is unaffected by adding the
diodes. On-resistance increases by a small amount at
low supply voltages. Maximum supply voltage (V+)
must not exceed 6V.
Adding protection diodes causes the logic thresholds
to be shifted relative to the power-supply rails. This can
be significant when low supply voltages (+5V or less)
are used. With a +5V supply, TTL compatibility is not
guaranteed when protection diodes are added. Driving
IN1 and IN2 all the way to the supply rails (i.e., to a
diode drop higher than the V+ pin, or to a diode drop
lower than the GND pin) is always acceptable.
Protection diodes D1 and D2 also protect against some
overvoltage situations. With Figure 1’s circuit, if the sup-
ply voltage is below the absolute maximum rating, and
if a fault voltage up to the absolute maximum rating is
applied to an analog signal pin, no damage will result.
