Low RON Low Voltage Dual SPDT Bi-directional Analog Switch

General 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 demultiplexer by select pins. The device features ultra-low R_ON of 1.35Ω maximum at 4.5V V_CC and will operate over the wide V_CC range of 1.65V to 5.5V. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The select input is TTL-level compatible.
