Description
The FSA2156 is a high-performance Single-Pole Single-
Throw (SPST) analog switch that features ultra low R_ON
of 0.4Ω (typ.) at 2.7V V_CC. 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.
