Notes:

A. Includes test lead and test apparatus capacitance.

B. Waveform 1 is for an output with input set up as a low and device coming out or into 3-state via DIR control.

Waveform 2 is for an output with input set up as a high and device coming out or into 3-state via DIR control.

C. All pulses are supplied at pulse repetition rate • 10 MHz.

D. tPLZ and tPHZ are the same as tdis.

E. tPZL and tPZH are the same as tEN.

F. tPLH and tPHL are the same as tPD.

G. VCCI is the VCC associated with the input.

F. VCCO is the VCC associated with the output.
