Notes:
A. C_L includes probe and jig capacitance.
B. 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.
C. All input impulses are supplied by generators having these characteristics: PRR ≤10 MHz, Z_O = 50Ω, t_R ≤2.0ns, t_F ≤2.0ns.
D. The outputs are measured one at a time with one transition per measurement.
E. t_PLZ and t_PHZ are the same as t_dis
F. t_PZL and t_PZH are the same as t_en
G. t_PLH and t_PHL are the same as t_pd
