Functional Description

The 74F827 and 74F828 are line drivers designed to be

employed as memory address drivers, clock drivers and

bus-oriented transmitters/receivers which provide

improved PC board density. The devices have 3-STATE

outputs controlled by the Output Enable (OE) pins. The

outputs can sink 64 mA and source 15 mA. Input clamp

diodes limit high-speed termination effects.
