Quiet Series
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
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series fea-
tures GTO
addition to a split ground bus for superior performance.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
