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 tPLZ and tPZL are the same as tPD.

E. tPZL is measured at VM.

F. tPLZ is measured at VOL +V∆.

D. A Thevenin equivalent load may be used in place of VCC X 2 and resistor divider.
