8.3.6.2 TMUX13xxA is Powered, Channel is Selected, and the Input Signal is Greater Than VDD (VDD = 5V, VINPUT = 5.5V)

The injection current control circuitry is fully active when the channel is unselected and an overvoltage event is present (overvoltage being defined as 0.5V above the supply rail). However, in situations where the channel is selected and an overvoltage event occurs, this protection circuitry will still be partially active. In this instance, a portion of the injected current will be redirected through the protection circuitry to GND, but will not be a full shunt. So, some current will also flow through the source to drain path. This allows the device to tolerate overvoltage conditions in the event of the channel being selected, but precautions are still necessary to protect the device from overcurrent events such as implementing a current limiting resistor to keep the device below the maximum continuous source and drain current specification.
