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
≤ 10 MHz, ZO = 50Ω, tr ≤2ns, tr ≤2ns.
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 tdis.
tPLH and tPHL are the same as tdis.
