FSA2268T: Low Voltage Dual SPDT (0.4 Ohm) Analog Switch with 16KV ESD

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-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 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.”
