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.
