The TS5A26542 is a dual single-pole double-throw (SPDT) analog switch that is designed to operate from 2.25V to 5.5 V. The device offers a low ON-state resistance with an excellent channel-to-channel ON-state resistance matching, and the break-before-make feature to prevent signal distortion during the transferring of a signal from one path to the another. The device has excellent total harmonic distortion (THD) performance and consumes very low power. These features make this device suitable for portable audio applications.

The TS5A26542 has a separate logic supply pin (VIO) that operates from 1.65 V to 1.95 V. VIO powers the control circuitry, which allows the TS5A26542 to be controlled by 1.8-V signals.
