G. t PLH and t PHL are the same as t pd .
C. All input pulses are supplied by generators having the following characteristics: PRR 10 MHz, Z O = 50 , t r 2 ns, t f 2 ns.
D. The outputs are measured one at a time with one transition per measurement.
B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
E. t PLZ and t PHZ are the same as t dis .
F. t PZL and t PZH are the same as t en .
C L = 30 pF
t PLH
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
