The 1KΩ load resistors should be connected between

outputs and VCC line and the 50pF load capacitors

should be connected between outputsand GND line.

All inputs except OE input should be connected to VCC

line or GND line such that outputs will be in low logic

level while OE input is held low.

tPHZ, tPZH

The 1KΩ load resistors and the 50pF load capacitors

should be connected between each output and GND

line.

All inputs except OE input should be connected to VCC

or GND line such that output will be in high logic level

while OE input is held low.
