Figure 2. Load Circuit and Voltage Waveforms

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.

C. All inputs pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50Ω, tr ≤ 2 ns, tf ≤ 2 ns.

D. The outputs are measured one at a time with one transition per measurement.

E. tPLZ and tPHZ are the same as tdis.

F. tPZL and tPZH are the same as tten.

G. tPLH and tPHL are the same as tpd.
