10-Bit Buffers/Line Drivers
General Description
Features
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.
■ 3-STATE output
■ 74F828 is inverting
The 74F828 is an inverting version of the 74F827.
