FSA1259 / FSA1259A Rev. 1.0.6

Description

The FSA1259/FSA1259A is a high-performance, dual,

Single-Pole / Single-Throw (SPST) analog switch. The

device features ultra-low R

operates over the wide V

The FS1259A allows for reduced input thresholds on

the select pins.

The device is fabricated with sub-micron CMOS

technology to achieve fast switching speeds and is

designed for break-before-make operation.
