The FSA2268 is a high-performance, dual Single Pole Double Throw (SPDT) analog switch that features ultra-low R_ON of 0.4W (typical) at 3.0V V_CC. The FSA2268 operates over a wide V_CC range of 1.65V to 4.3V and is designed for break-beforemake operation. The select input is TTL-level compatible. The FSA2268 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. The FSA2268T includes termination resistors that improve noise immunity during overshoot excursions, off-isolation coupling, or “pop-minimization.”
