General Description
The MAX4610/MAX4611/MAX4612 quad, low-voltage,
single-pole/single-throw (SPST) analog switches are
pin-compatible with the industry-standard 74HC4066
analog switch. On-resistance (100Ωmax) is matched
between switches to 4Ωmax and is flat (4Ωmax) 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 2nA at TA= +85°C.
The MAX4610 has four normally open (NO) switches,
and the MAX4611 has four normally closed (NC)
switches. The MAX4612 has two NO switches and two
NC switches. These CMOS switches operate from a
single +2V to +12V supply. All digital inputs have +0.8V
and +2.4V logic thresholds, ensuring TTL/CMOS-logic
compatibility when using a single +5V supply.

(V+ = +5V ±10%, VIN_H = 2.4V, VIN_L = 0.8V, TA= TMIN to TMAX, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

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 13V.
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.

Operating Considerations for
High-Voltage Supply
The MAX4610/MAX4611/MAX4612 are pin-compatible
with the industry-standard 74HC4066 and the
MAX4066, and are optimized for +5V single-supply
operation. The MAX4610 family is capable of +12V sin-
gle-supply operation with some precautions. The
absolute maximum rating for V+ is +13.2V (referenced
to GND). When operating near this region, bypass V+
with a minimum 0.1µF capacitor to ground as close to
the IC as possible.
Caution: The absolute maximum V+ to V- differential
voltage is 13.0V. Typical ±6V or 12V supplies with
±10% tolerances can be as high as 13.2V. This volt-
age can damage the MAX4610/MAX4611/MAX4612.
Even ±5% tolerance supplies may have overshoot or
noise spikes that exceed 13.0V.
