The TMUX7411F, TMUX7412F, and TMUX7413F enter into fault mode when any of the input signals on the source (Sx) pins exceed VDD or VSS by a threshold voltage VT. Under the overvoltage condition, the switch input experiencing the fault automatically turns off regardless of the logic status, and the source pin becomes high impedance with negligible amount of leakage current flowing through the switch. When the fault channel is turned-on by the select control logic (SELx), the drain pin (Dx) left floating and the final voltage is determined by the circuitry connected to the drain pin.
In the fault mode, the general fault flag (FF) is asserted low.
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 VDD and VSS at all time since no overvoltage protection is implemented on the drain pin.
