8.4.2 Fault Mode

The TMUX7462F enters into the Fault mode when any of the input signals on the source (Sx) pins exceed VFP or VFN by a threshold voltage VT. The switch input experiencing the fault automatically turns off, and the source pin becomes high impedance with negligible amount of leakage current flowing through the switch under the overvoltage condition. For how the drain pin (Dx) behavior under the Fault mode can be programmed, refer to Section 8.3.2.4. The general fault flag (FF) is asserted low in the Fault mode.

The overvoltage protection is provided only for the source (Sx) input pins. The drain (Dx) pin, if used as signal input, must stay in between VFP and VFN at all time since no overvoltage protection is implemented on the drain pin.
