B. Input rise and fall times are 3 ns.
C. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.
D. Input rise and fall times are 3 ns. Pulse duration is 150 ns < t
