Notes: 1. Input waveform: PRR ≤ 1 MHz, Zo = 50 Ω, tr ≤ 3 ns, tf ≤ 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.
