Protecting Against Fault
Conditions
Fault conditions occur when power supplies are turned
off when input signals are still present, or when over-
voltages occur at the inputs during normal operation. In
either case, source-to-body diodes can be forward
biased and conduct current from the signal source. If

steady state output with switch on. Feedthrough via
gate capacitance may result in spikes at leading and
trailing edge of output waveform.
