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