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.
