Texas Instruments' TMUX1072 are high-speed, 2-channel, 2:1, analog switches with integrated overvoltage detection and powered-off protection. These devices are bidirectional and can be used as a 2:1 or 1:2 switches while supporting signals beyond V_CC up to 5.5 V.

The protection on the I/O pins of the TMUX1072 tolerates a maximum of 18 V with automatic shutoff circuitry to prevent damage to system components behind the switch. This protection is used for power sequencing. There are boards in the system that are powered up before others are ready to receive signals. These devices detect overvoltage and overtemperature events, and provide an open-drain output signal through the FLT-pin.
