The FSA6157 is a high-performance, Single Pole Double Throw (SPDT) analog switch that features a low R_ON of 0.8W (typical) at 2.7V supply. The FSA6157 operates over a wide V_CC range of 1.65V to 4.3V and is designed for break-before-make operation. The select input is TTLlevel compatible.

The FSA6157 features very low quiescent current even when the control voltage is lower than the V_CC supply. This feature suits mobile handset applications by allowing direct interface with baseband processor general-purpose I/Os with minimal battery consumption.
