Notes:

1.

Input waveform: PRR

1 MHz, Zo = 50

Ω.

2.

Waveform–A is for an output with internal conditions such that the output is low
except when disabled by the output control.

3.

Waveform–B is for an output with internal conditions such that the output is high
except when disabled by the output control.

4.

The output are measured one at a time with one transition per measurement.
