Functional Diagram
Description
The CD54ACT623F3A is an octal bus transceiver that uti-
lizes Harris Advanced CMOS Logic technology. It is a non-
inverting three-state bidirectional transceiver-buffer that
allows for two-way transmission from “A” bus to “B” bus or
“B” bus to “A” bus depending on the logic levels of the Output
Enable (OE
AB
, OE
BA
) inputs.
The dual Output Enable provision gives these devices the
capability to store data by simultaneously enabling OE
AB
and OE
BA
. Each output reinforces its input under these con-
ditions, and when all other data sources to the bus lines are
at high-impedance, both sets of bus lines will remain in their
last states.
