Notes:
CL includes probe and jig capacitance.
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.
All input pulses are supplied by generators having the following characteristics: PRR ≤10Mz, ZO = 50Ω, tR ≤2.5ns, tF ≤2.5ns.
The outputs are measured one at a time with one transition per measurement.
tPLZ and tPHZ are the same as tDIS.
tPZL and tPZH are the same as tEN.
tPLH and tPHL are the same as tPD.
