Notes:
A. Includes test lead and test apparatus capacitance.
B. All pulses are supplied at pulse repetition rate ≤ 1 MHz.
C.The inputs are measured one at a time with one transition per measurement.
D. For the open drain device t_PLZ and t_PZL are the same as t_PD.
E. t_PZL is measured at V_M.
F. t_PLZ is measured at V_OL +V_∆.
D. A Thevenin equivalent load may be used in place of V_CC X 2 and resistor divider.
