The TMUX1072 is a high-speed, 2-channel, 2:1, analog switch with integrated overvoltage detection and powered off protection. The device is bidirectional and can be used as a 2:1 or 1:2 switch while supporting signals beyond VCC 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. Some boards in the system may be powered up before others are ready to receive signals. The device detects overvoltage and overtemperature events, and provides an open drain output signal through the FLT pin.
