NOTES: A. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, tr and tf ≤ 2 ns, and
duty cycle = 50%.
B. CL includes probe and jig capacitance.
C. All diodes are 1N914 (or equivalent).
D. The outputs are measured one at a time, with one input transition per measurement.
