Overview
The TS5A3359DCURG4 is a bidirectional, single-channel, single-pole triple-throw (SP3T) analog switch produced by Texas Instruments. This device is designed to operate from 1.65 V to 5.5 V, making it versatile for various applications. It maintains excellent signal integrity through its low ON-state resistance, excellent ON-state resistance matching, and low total harmonic distortion (THD). The TS5A3359 also features specified break-before-make switching to prevent signal distortion during channel switching. It consumes very low power and provides isolation when the power supply (VCC) is set to 0 V.
