Overview
The NC7SB3157 / FSA3157, produced by onsemi, is a high-performance, single-pole / double-throw (SPDT) analog switch or 2:1 multiplexer / de-multiplexer bus switch. Fabricated with advanced sub-micron CMOS technology, this device achieves high-speed enable and disable times and low on resistance. It features break-before-make select circuitry to prevent signal disruption on the B Port during select pin switching. The device operates over a broad VCC range of 1.65 to 5.5V, with control inputs tolerant of voltages up to 5.5V.
