Description
The FSA2257 is a high-performance bi-directional dual
Single-Pole/Double-Throw (SPDT) analog switch. This
switch can be configured as either a multiplexer or a de-
multiplexer by select pins. The device features ultra-low
R_ON of 1.3Ω maximum at 4.5V V_CC and operates over
the wide V_CC range of 1.65V to 5.5V. The device is fabri-
cated with submicron CMOS technology to achieve fast
switching speeds and is designed for break-before-make
operation. The select input is TTL-level compatible.
