Notes:

A. Includes test lead and test apparatus capacitance.

B. Output Waveform 1 depends on the internal QN node being low and behaves in this manner based on OE pin.

Output Waveform 2 depends on the internal QN node being high and behaves in this manner based on OE pin.

C. All pulses are supplied at pulse repetition rate

≤ 10MHz

D. Inputs are measured separately one transition per measurement

E. tPLH and tPHL are the same as tPD
