74AC843  74ACT843
9-Bit Transparent Latch
General Description
The ’AC ’ACT843 bus interface latch is designed to elimi-
nate the extra packages required to buffer existing latches
and provide extra data width for wider address data paths
The ’AC ’ACT843 is functionally and pin compatible with
AMD’s Am29843
