Notes: A . Includes test lead and test apparatus capacitance.

B. Output Waveform 1 depends on the internal Q

N

node being low and behaves in this manner based on OE pin.

Output Waveform 2 depends on the internal Q

N

node being high and behaves in this manner based on OE pin.

C. All pulses are supplied at pulse repetition rate ≤ 10 MHz

D. Inputs are measured separately one transition per measurement

E. t
