74ACTQ843 Quiet Series鈩?9-Bit Transparent Latch with 3-STATE Outputs
March 1990
Revised December 1998
74ACTQ843
Quiet Series鈩?9-Bit Transparent Latch
with 3-STATE Outputs
General Description
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鈩?technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series fea-
tures GTO鈩?output control and undershoot corrector in
addition to a split ground bus for superior performance.
Features
s
Guaranteed simultaneous switching noise level and
dynamic threshold performance
s
Guaranteed pin-to-pin skew AC performance
s
Inputs and outputs on opposite sides of package for
easy interface with microprocessors
s
Improved latch-up immunity
s
Outputs source/sink 24 mA
s
ACTQ843 has TTL-compatible inputs
s
Functionally and pin-compatible to AMD鈥檚 AM29843
s
3-STATE outputs for bus interfacing
