8.5 Input and Output Leakage Current Under Overvoltage Fault
If any of the source pin voltage goes above the supplies (VDD or VSS), the overvoltage protection feature of the
TMUX7411F, TMUX7412F, and TMUX7413F is triggered to turn off the switch under fault, keeping the fault
channel in 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 8-4) or abnormal operating condition (Figure 8-5). 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.
