Analog multiplexer provides overvoltage overtemperature protection

The Texas Instruments TMUX1072 is a high-speed, two-channel, 2:1, analog switch with integrated overvoltage detection and powered off protection. This device is bidirectional and can be utilised as a 2:1 or 1:2 switch while maintaining signals beyond VCC up to 5.5V. The protection on the I/O pins of the device tolerates a maximum of 18V with automatic shutoff circuitry to stop damage to system components behind the switch. This protection is used for power sequencing. Some boards in the system may be powered up prior to others being ready to receive signals. The device identifies overvoltage and overtemperature events and offers an open drain output signal through the FLT pin.
