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
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
E. 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.
F. The outputs are measured one at a time with one input transition per measurement.
