7.4 Input and Output Leakage Current Under Overvoltage Fault

If any of the source pin voltage goes above the supplies (VDD or VSS) by one threshold voltage (VT), then the overvoltage protection feature of the TMUX7436F is triggered to turn off the switch under fault, keeping the fault channel in a high-impedance state. IS(FA) and ID(FA) denotes the input and output leakage current under overvoltage fault conditions, respectively. When the overvoltage fault occurs, the supply (or supplies) can either be in normal operating condition (Figure 7-4) or abnormal operating condition (Figure 7-5). During abnormal operating condition, the supply (or supplies) can either be unpowered (VDD= VSS = 0 V) or floating (VDD= VSS = no connection), and remains within the leakage performance specifications.
