NOTES: A. All input pulses are supplied by generators having the following characteristics: PRR ≤ 45 MHz, ZO = 50 Ω, tr ≤ 1 ns, tf ≤ 1 ns.
B. Waveform 1 is for a Y output with internal conditions such that the output is high except when disabled by the output control, and
for a Y output with internal conditions such that the output is low except when disabled by the output control.
C. The outputs are measured one at a time with one transition per measurement.
