0.75-Ohm SPDT Analog Switch With Input Logic Translation



The TS5A6542 is a single-pole double-throw (SPDT) analog switch that is designed to operate from 2.25 V 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 distorion during the transferring of a signal from one path to 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 TS5A6542 has a separate logic supply pin (VIO) that is characterized to operate from 1.65 V to 1.95 V. VIO powers the control circuitry, which allows the TS5A6542 to be controlled by 1.8-V signals.
