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

The NC7SB3157 / FSA3157 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-beforemake 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 VCC operating range. The control input tolerates voltages up to 5.5V, independent of the VCC operating range.
