Notes: 1. Input waveform: PRR ≤ 1 MHz, Zo = 50 Ω, t_r ≤ 3 ns, t_f ≤ 3 ns
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 is measured one at a time with one transition per measurement.
