Notes: 1. Input waveform : PRR ≤ 10 MHz, Zo = 50 Ω, duty cycle 50%.
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.
