Notes:

1. CL includes probe and jig capacitance.

2. 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
