Quad, Low-Voltage, SPST Analog Switches  
General Description  
Features  
The MAX4521/MAX4522/MAX4523 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 (12Ω max) over the specified  
signal range. Each switch can handle rail-to-rail analog  
signals. The off-leakage current is only 1nA at +25°C  
and 10nA at +85°C.

The MAX4521 has four normally closed (NC) switches,  
and the MAX4522 has four normally open (NO) switch-  
es. The MAX4523 has two NC switches and two NO  
switches.

ꢁG211/ꢁG212/ꢁG213  
These CMOS switches can operate with dual power  
supplies ranging from 2ꢀ to ꢁꢀ or a single supply  
between +2ꢀ and +12ꢀ. They are fully specified for sin-  
gle +2.7ꢀ operation.

Ordering Information  
All digital inputs have +0.8ꢀ and +2.4ꢀ logic thresh-  
olds, ensuring TTL/CMOS-logic compatibility when  
using 5ꢀ or a single +5ꢀ supply.
