Notes: 1. t_r ≤ 3 ns, t_f ≤ 3 ns
2. Input waveform: PRR ≤ 1 MHZ, duty cycle 50%
3. Waveform-A is for an output with internal conditions such that the output is low except
when disabled by the output control.
4. Waveform-B is for an output with internal conditions such that the output is high except
when disabled by the output control.
