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.
