#
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.  
Features  
Y
’ACT843 has TTL-compatible inputs  
Y
TRI-STATE outputs for bus interfacing  
É
The ’AC/’ACT843 is functionally and pin compatible with  
AMD’s Am29843.
