74ACT843
9-Bit Transparent Latch
General Description
The ACT843 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.
Features
a73 TTL compatible inputs
a73 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. (SPC not available in Tape and Reel.)
