Note 1 )Waveform1 is for an output with internal conditions such that the output is low except when disabled by the output control.

Waveform2 is for an output with internal conditions such that the output is high except when disabled by the output control

Note 2) All input pulses are supplied by generators having the following characteristics:

PRR

⊆ 10Mhz, Z

⊆ 2ns.

Note 3) The output are measured one at a time with one transition per measurement.
