Notes: 1. Input waveform: PRR ⤠1 MHz, Zo = 50 â¦, t ⤠3 ns, t ⤠3 ns
2. WaveformâA is for an output with internal conditions such that the output is low except when disabled
by the output control.
3. WaveformâB 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.
