Overview

The FSA2156 is a high-performance Single-Pole Single-Throw (SPST) analog switch that features ultra low RON of 0.4Ω (typical) at 2.7V VCC. The FSA2156 operates over the wide VCC range of 1.65V to 4.3V and is fabricated with sub-micron CMOS technology to achieve fast switching speeds. The select input is TTL-level compatible. FSA2156 features very low quiescent current even when the control voltage is lower than the VCC supply. This feature facilitates longer battery life in mobile handset applications and allows for the direct interface with baseband-processor, general-purpose I/Os.
