includes probe and jig capacitance.
B. Waveform 1 is for an output with internal conditions
such that the output is LOW except when disabled by the
output control.
Waveform 2 is for an output with internal conditions
such that the output is HIGH except when disabled by
the output control.
C. All input pulses are supplied by generators having the
following characteristics: PRR
