These 10-bit bus transceivers are designed for
asynchronous communication between data
buses. The control-function implementation
allows for maximum flexibility in timing.
SN54BCT29862B . . . FK PACKAGE
(TOP VIEW)
These devices allow data transmission from the A
bus to the B bus or from the B bus to the A bus,
depending upon the logic levels at the
output-enable (OEBA and OEAB) inputs.
