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