B. 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.
C. All input pulses are supplied by
generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50
Ω, tr ≤ 2.5 ns, tf ≤ 2.5 ns.
D. The outputs are measured one at a
time with one input transition per measurement.
