1 General Description

The AS1744/AS1745 are high-speed, low-voltage, dual

single-pole/double-throw (SPDT) 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 +1.8 to

+5.5V supply, are differentiated by inverted logic, and

support break-before-make switching.

With low ON-resistance (RON), RON matching, and RON

flatness, the devices can accurately switch signals for

sample and hold circuits, digital filters, and op-amp gain

switching networks.

The devices are available in a 10-pin MSOP package

and a 10-pin TDFN package.
