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.
