APPLICATIO S I FOR ATIO
Switching Time Test Circuit
Switch output waveform shown for VS = constant with
logic input waveform as shown. Note that VS may be + or
– as per switching time test circuit. VO is the steady state
output switch on. Feedthrough via gate capacitance may
result in spikes at leading and trailing edge of output
waveform.
