3 Description

This device contains eight independent inverting line

drivers with 3-state outputs and Schmitt-trigger inputs.

Each channel performs the Boolean function Y = A

in positive logic. The channels are grouped in sets of

four, with one OE pin controlling each set. The outputs

can be put into a hi-Z state by applying a high on the

associated OE pin.
