Switching Time Test Circuit
Switch output waveform shown for 5 = constant with
S
logic input waveform as shown. Note that 5 may be
S
+ve or -ve as per switching times test circuit. 5 is the
O
steady state output with switch on. Feedthrough via
gate capacitance may result in spikes at leading and
trailing edge of output waveform.
