NOTES: A. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by pulse generators having the
following characteristics: PRR = 1 MHz, ZO = 50
, tr
≤
6 ns, tf
≤
6 ns.
B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
C. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. For tPLZ
and tPHZ, VOL and VOH are measured values.
