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.

The protection on the I/O pins of the TMUX1072 can

tolerate up to 20 V with automatic shutoff circuitry to

protect system components behind the switch. This

protection is also used for power sequencing where

some boards in the system maybe powered up

before others are ready to receive signals. The

device also detects overvoltage and overtemperature

events and provides an open drain output signal

through the FLT pin.
