, tr
1 ns, tf
1 ns.
B. Waveform 1 is for a Y output with internal conditions such that the output is high except when disabled, and for a Y output with internal
conditions such that the output is low except when disabled.
C. The outputs are measured one at a time with one transition per measurement.
