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.
