Description

The FSA2156 is a high-performance Single-Pole Single- Throw (SPST) analog switch t hat features ultra low R ON of 0.4  (typical) at 2.7V V CC. The FSA2156 operates over the wide V CC 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 V CC supply. This feature facilitates longer ba ttery life in mobile handset applications and allows for the direct interface with baseband-processor, general-purpose I/Os.
