LOAD CIRCUIT AND VOLTAGE WAVEFORMS
PARAMETER MEASUREMENT INFORMATION (A PORT)
NOTES:
A. C
B. Waveform 1 is for an output with internal conditions such that the output is LOW except when disabled by the output control.
C . All input pulses are supplied by generators having the following characteristics: PRR ≤ 10MHz; Zo = 50Ω; t
D. The outputs are measured one at a time with one transition per measurement.
