CL includes probe and jig capacitance.
All diodes are 1N3064 or equivalent.
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.
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.
All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO ≈ 50 Ω ; tr and tf ≤ 7 ns for Series SN5414 and SN7414 devices and tr and tf ≤ 2.5 ns for Series SN54S14 and SN74S14 devices.
The outputs are measured one at a time with one input transition per measurement.

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.
Phase relationships between inputs and outputs have been chosen arbitrarily for these examples.
All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO ≈ 50 Ω, tr ≤ 1.5 ns, tf ≤ 2.6 ns.
The outputs are measured one at a time with one input transition per measurement.
