A. CL includes probe and test-fixture capacitance.
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. Phase relationships between waveforms were chosen arbitrarily. All input pulses
are supplied by generators having the following characteristics: PRR ≤ 1 MHz,
ZO = 50 Ω, tr = 6 ns, tf = 6 ns.
D. The
outputs are measured one at a time with one input transition per
measurement.
