The 1K鈩?load resistors should be connected between
outputs and V
CC
line and the 50pF load capacitors
should be connected between outputsand GND line.
All inputs except OE input should be connected to V
CC
line or GND line such that outputs will be in low logic
level while OE input is held low.

The 1K鈩?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 V
CC
or GND line such that output will be in high logic level
while OE input is held low.
