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
