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