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 input pulses are supplied by generators having the

following characteristics: PRR ≤ 10 MHz, ZO = 50Ω,

tr ≤ 2ns, tf ≤ 2ns, measured from 10% to 90%, unless

otherwise specified.

D. The outputs are measured one at a time with one

transition per measurement.
