Overview
The TS3A24157RSER is a bidirectional, 2-channel, single-pole double-throw (SPDT) analog switch designed and manufactured by Texas Instruments. This device is optimized for low-voltage applications, operating from 1.65 V to 3.6 V. It features low ON-state resistance, excellent ON-state resistance matching, and a break-before-make switching mechanism to prevent signal distortion. The TS3A24157RSER is suitable for a wide range of applications requiring high signal integrity and low power consumption.
