2.3 Leakage Current

All multiplexers will have some form of leakage current that can be injected into the application, some more and some less. What can be problematic during an event that imparts a high common mode voltage onto the inputs of a device is that the leakage current will certainly increase and if not accounted for in the system, can potentially affect the accuracy of the application.
