10-Bit Buffers/Line Drivers
General Description
The 74F827 and 74F828 10-bit bus buffers provide high
performance bus interface buffering for wide data/address
paths or buses carrying parity. The 10-bit buffers have
NOR output enables for maximum control flexibility.
The 74F828 is an inverting version of the 74F827.

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.
