• 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.
