Notes:
A. Includes test lead and test apparatus capacitance.
B. All pulses are supplied at pulse repetition rate ≤10 Hz.
C. Inputs are measured separately, one transition per measurement.
D. tPLH and tPHL are the same as tPD.
E. Transition times tt, ttlh, tthl are measured from the 10% to 90% or 90% to 10% of the appropriate waveform.
