The TS5A12301E device is a bidirectional, 1-channel, 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 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 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 control input (IN) pin can be connected to low-voltage GPIOs, allowing it to be controlled by 1.8-V signals. The TS5A12301E has ±15-kV air-gap discharge and ±8-kV contact discharge ESD protection for the COM port to GND, which makes it compliant with the IEC Level 4 ESD standard (IEC 61000-4-2).
