The voltages on TMUX7462F's source input pins 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 V_T, the FF output is pulled-down to below V_OL. The FF pin is an open-drain output, and external pull-up resistors of 1 kΩ are 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.
