74ACTQ843  
Quiet Series 9-Bit Transparent Latch  
with 3-STATE Outputs  
General Description  
Features  
Guaranteed simultaneous switching noise level and  
The ACTQ843 bus interface latch is designed to eliminate  
the extra packages required to buffer existing latches and  
provide extra data width for wider address/data paths. The  
ACTQ843 utilizes Fairchild FACT Quiet Series technol-  
ogy to guarantee quiet output switching and improved  
dynamic threshold performance. FACT Quiet Series fea-  
tures GTO output control and undershoot corrector in  
addition to a split ground bus for superior performance.  
dynamic threshold performance  
Guaranteed pin-to-pin skew AC performance  
Inputs and outputs on opposite sides of package for  
easy interface with microprocessors  
Improved latch-up immunity  
Outputs source/sink 24 mA  
ACTQ843 has TTL-compatible inputs  
Functionally and pin-compatible to AMD’s AM29843  
3-STATE outputs for bus interfacing
