Notes: 1. All input pulses are supplied by generators having the following characteristics:
PRR ⤠10 MHz, Zo = 50 â¦, tr ⤠2.5 ns, tf ⤠2.5 ns.
2. Waveform â A is for an output with internal conditions such that the output is low
except when disabled by the output control.
3. Waveform â 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.
