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
Y TRI-STATE output
Y ’F828 is inverting
Y Direct replacement for AMD’s Am29827 and Am29828
