Low Voltage SPDT Analog Switch or 2:1 Multiplexer/Demultiplexer Bus Switch

The FSA3157B is a high-performance, Single-Pole / Double-Throw (SPDT) analog switch or 2:1 multiplexer / de-multiplexer bus switch. The device is fabricated with advanced sub-micron CMOS technology to achieve high-speed enable and disable times and low on resistance. The break-before- make select circuitry prevents disruption of signals on the B Port due to both switches temporarily being enabled during select pin switching. The device is specified to operate over the 1.65 to 5.5V VCCoperating range. The control input tolerates voltages up to 5.5V, independent of the VCC operating range.
