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.
