Description
The FSA2268 is a high-performance, dual Single Pole
Double Throw (SPDT) analog switch that features ultra-
low RON of 0.4Ω (typical) at 3.0V VCC. The FSA2268
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 FSA2268 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 FSA2268T includes termination resistors that
improve noise immunity during overshoot excursions,
off-isolation coupling, or “pop-minimization.”
