74ACTQ843
Quiet Series
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
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.
Features
I
Guaranteed simultaneous switching noise level and
dynamic threshold performance
I
Guaranteed pin-to-pin skew AC performance
I
Inputs and outputs on opposite sides of package for
easy interface with microprocessors
I
Improved latch-up immunity
I
Outputs source/sink 24 mA
I
ACTQ843 has TTL-compatible inputs
I
Functionally and pin-compatible to AMD’s AM29843
I
3-STATE outputs for bus interfacing
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
