It features ultra-low RON of 0.4Ω (typical) at 3.0V VCC. The FSA2271 operates over a wide VCC range of 1.65V to 4.3V and is fabricated with sub-micron CMOS technology to achieve fast switching speeds. Designed for break-before-make operation, the FSA2271 select input is TTL level compatible. The FSA2271 features very low quiescent current, even when the control voltage is lower than the VCC supply. This feature is optimized for the mobile handset applications, allowing direct interface with baseband processor general-purpose I/Os with minimal battery consumption. The FSA2271T includes termination resistors that improve noise immunity during overshoot excursions, “pop-minimization,” or off-isolation coupling.
