1. All input pulses are supplied by generators having the following characteristics :
PRR ⤠10 MHz, Zo = 50 â¦, tr ⤠2.0 ns, tf ⤠2.0 ns. (VCC = 2.5±0.2 V)
PRR ⤠10 MHz, Zo = 50 â¦, tr ⤠2.5 ns, tf ⤠2.5 ns. (VCC = 2.7 V, 3.3±0.3 V)
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.
