Low-Voltage, Quad, SPST
CMOS Analog Switches
General Description
The MAX4610/MAX4611/MAX4612 are quad, low-volt-
age, single-pole/single-throw (SPST) analog switches.
On-resistance (100Ω, max) is matched between switch-
es to 4Ω, max and is flat (4Ω, max) over the specified
signal range. Each switch handles V+ to GND analog
signal levels. Maximum off-leakage current is only 1nA
at T
A
= +25°C and 2nA at T
A
= +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.

Note 1:
Signals on NO_, NC_, COM_, or IN_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to
maximum current rating.
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.
