Overview
The TS3A4751PWRG4 is a bidirectional, 4-channel, normally open (NO) single-pole single-throw (SPST) analog switch produced by Texas Instruments. This device operates from a single supply voltage ranging from 1.6 V to 3.6 V, making it versatile for various low-voltage applications. It features 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, enhancing its compatibility with modern digital systems.
