±15kV ESD-Protected, Quad,
Low-Voltage, SPST Analog Switches
General Description
The MAX4551/MAX4552/MAX4553 are quad, low-volt-
age, single-pole/single-throw (SPST) analog switches.
Each switch is protected against ±15kV electrostatic
discharge (ESD) shocks, without latchup or damage.
On-resistance (100Ω max) is matched between switch-
es to 4Ω max, and is flat (8Ω max) over the specified
signal range. Each switch can handle Rail-to-Rail
®
ana-
log signals. The off-leakage current is only 1nA at
+25°C and 10nA at +85°C.
The MAX4551 has four normally closed (NC) switches,
and the MAX4552 has four normally open (NO) switch-
es. The MAX4553 has two NC and two NO switches.
These CMOS switches can operate with dual power
supplies ranging from ±2V to ±6V or a single supply
between +2V and +12V. They are fully specified for sin-
gle +2.7V operation.
All digital inputs have +0.8V and +2.4V logic thresh-
olds, ensuring TTL/CMOS-logic compatibility when
using ±5V or a single +5V supply.

Note 1:
Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- 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.
