includes probe and jig capacitance.
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.
All input pulses are supplied by generators having the following characteristics: PRR < 10 MHz, Zo = 50
