9.3.3 Overvoltage Fault Flags

The voltages on the source input pins of the TMUX7411F, TMUX7412F, and TMUX7413F are continuously monitored, and the status of whether an overvoltage condition occurs is indicated by an active low general fault flag (FF). The voltage on the FF pin indicates if any of the source input pins are experiencing an overvoltage condition. If any source pin voltage exceeds the fault supply voltages by a VT, the FF output is pulled-down to below VOL.

The FF pin is an open-drain output and an external pull-up resistor of 1 kΩ is recommended. The pull-up voltage can be in the range of 1.8 V to 5.5 V, depending on the controller voltage the device interfaces with.
