NOTES: A. CL includes probe and jig capacitance.
B. All diodes are 1N3064 or equivalent.
C. 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.
D. S1 and S2 are closed for tPLH, tPHL, tPHZ, and tPLZ; S1 is open and S2 is closed for tPZH; S1 is closed and S2 is open for tPZL.
E. All input pulses are supplied by generators having the following characteristics: PRR
≤ 1 MHz, ZO ≈ 50 ; tr and tf ≤ 7 ns for Series
54/74 devices and tr and tf ≤ 2.5 ns for Series 54S/74S devices.
F. The outputs are measured one at a time with one input transition per measurement.
