Description
The FSA2156 is a high-performance Single-Pole Single-
Throw (SPST) analog switch that 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 battery life in mobile handset
applications and allows for the direct interface with
baseband-processor, general-purpose I/Os.
