Notes : 1. Input waveform : PRR â¤ 1 MHz, duty cycle 50%, tr â¤ 6 ns, tf â¤ 6 ns

2. Waveformâ A is for an output with internal conditions such that the

output is low except when disabled by the output control.

3. Waveformâ 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.
