DESCRIPTION/ORDERING INFORMATION
The TS3A4751 is a low ON-state resistance (ron), low-voltage, quad, single-pole/single-throw (SPST) analog
switch that operates from a single 1.6-V to 3.6-V supply. This device has fast switching speeds, handles
rail-to-rail analog signals, and consumes very low quiescent power.
The digital input is 1.8-V CMOS compatible when using a 3-V supply.
The TS3A4751 has four normally open (NO) switches. The TS3A4751 is available in a 14-pin thin shrink
small-outline package (TSSOP) and in space-saving 14-pin SON (RGY) and micro QFN (RUC) packages.
