Overview
The TS3A24157RSERG4 is a bidirectional, 2-channel, single-pole double-throw (SPDT) analog switch produced by Texas Instruments. This device is designed to operate from a single supply voltage ranging from 1.65 V to 3.6 V, making it versatile for various low-voltage applications. The TS3A24157 offers low ON-state resistance, excellent ON-state resistance matching, and a break-before-make switching feature to prevent signal distortion during channel switching. It is particularly suitable for applications requiring low power consumption and minimal signal distortion, such as portable audio and video signal routing.
