Texas Instruments  TS3A4751PWR

The TS3A4751 device is a bidirectional, 4-channel, normally open (NO) single-polesingle-throw (SPST) analog switch that operates from a single 1.6-V to 3.6-V supply. This devicehas fast switching speeds, handles rail-to-rail analog signals, and consumes very low quiescentpower.

The digital input is 1.8-V CMOS compatible when using a 3-V supply.

The TS3A4751 device has four normally open (NO) switches. The TS3A4751 is available in a14-pin thin shrink small-outline package (TSSOP) and in space-saving 14-pin VQFN (RGY) and microX2QFN (RUC) packages.
