Description
The FSA6157 is a high-performance, Single Pole Double
Throw (SPDT) analog switch that features a low RON of
0.8Ω (typical) at 2.7V supply. The FSA6157 operates
over a wide VCC range of 1.65V to 4.3V and is designed
for break-before-make operation. The select input is TTL-
level compatible.
The FSA6157 features very low quiescent current even
when the control voltage is lower than the VCC supply.
This feature suits mobile handset applications by
allowing direct interface with baseband processor
general-purpose I/Os with minimal battery consumption.
The FSA6157T includes termination resistors to improve
the susceptibility to noise during overshoot excursions,
off-isolation coupling, or “pop-minimization.”
