Notes: 1. All input pulses are supplied by generators having the following characteristics:
PRR ≤ 10 MHz, Zo = 50 Ω, tr ≤ 2.5 ns, tf ≤ 2.5 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.
