Data Sheet
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 singlecell battery powered applications.

These highly-reliable devices operate from a 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.
