10-Bit Buffers Line Drivers
General Description
The ’F827 and ’F828 10-bit bus buffers provide high per-
formance 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 ’F827 and ’F828 are functionally- and pin-compatible to
AMD’s Am29827 and Am29828 The ’F828 is an inverting
version of the ’F827
Features

Functional Description
The ’F827 and ’F828 are line drivers designed to be em-
ployed as memory address drivers clock drivers and bus-
oriented transmitters receivers which provide improved PC
board density The devices have TRI-STATE outputs con-
trolled by the Output Enable (OE) pins The outputs can sink
64 mA (48 mA mil) and source 15 mA Input clamp diodes
limit high-speed termination effects
