Notes:
1. tr = 2.5 ns, tf = 2.5 ns
2. Input waveform : PRR = 10 MHz, duty cycle 50%
3. Waveform – A shows input conditions such that the output is "L" level when enable by the
output control.
4. Waveform – B shows input conditions such that the output is "H" level when enable by the
output control.
