1. All input pulses are supplied by generators having the following characteristics :
PRR ≤ 10 MHz, Zo = 50 Ω, tr ≤ 2.0 ns, tf ≤ 2.0 ns. (VCC = 2.5±0.2 V)
PRR ≤ 10 MHz, Zo = 50 Ω, tr ≤ 2.5 ns, tf ≤ 2.5 ns. (VCC = 2.7 V, 3.3±0.3 V)
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 outputs are measured one at a time with one transition per measurement.
