3 Description

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.
