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 ≤ 10 Hz. D. Inputs are measured separately one transition per measurement. E. tPLH and tPHL are the same as tPD. Figure 1. Load Circuit and Voltage Waveforms
