Note:
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.

NOTES:
1. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10MHz, ZO = 50 Ω, tr ≤ 2.5 ns, tf ≤ 2.5 ns.
2. The outputs are measured one at a time with one transition per measurement.
