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, Z
t
otherwise specified.
The outputs are measured one at a time with one
transition per measurement.
