General Description

The AS1751/AS1752/AS1753 are high-speed, low-volt age, quad single-pole/single-throw (SPST) analog switches.

Fast switching speeds, low ON-resistance, and low power consumption make these devices ideal for single cell battery powered applications. These highly-reliable devices operate from a single +1.6 to +3.6V supply, and are differentiated by the type and number of switches:

AS1751 - Four normally open (NO) switches

AS1752 - Four normally closed (NC) switches

AS1753 - Two NO switches and Two NC switches
