GND description
These devices contain four independent 2-input
positive-NOR buffers with open-collector outputs.
Open-collector outputs require resistive pullup to
perform correctly. They can deliver higher VOH
levels and commonly are used in wired-AND
applications. These devices perform the Boolean
functions Y = A B or Y = A + B in positive logic. OUTPUT
