Description
The FSA2156 is a high-performance Single-Pole
Single-Throw (SPST) analog switch that features ultra
low R
operates over the wide V
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
This feature facilitates longer battery life in mobile
handset applications and allows for the direct interface
with baseband-processor, general-purpose I/Os.
