  • TMUX1072  -  2-channel 2:1 analog switch offering powered-off & 18-V overvoltage protections, 1.8-V compatible logic inputs, & extended temperature range (–40°C to +125°C)


The TS5A23159 is a bidirectional 2-channel single-pole double-throw (SPDT) switch that is designed to operate from 1.65 V to 5.5 V. The device offers low ON-state resistance and excellent ON-state resistance matching with the break-before-make feature which prevents signal distortion during the transferring of a signal from one channel to another. The device has an excellent total harmonic distortion (THD) performance and consumes very low power. These features make this device suitable for a wide variety of portable applications including cell phones, audio devices, and instrumentation.
