Notes:
A. CL 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.
• All input impulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50Ω, tR ≤ 2.0ns, tF ≤ 2.0ns.
• 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
