Pin Descriptions
Functional Description
The 74FR543 contains two sets of D-type latches, with
separate input and output controls for each. For data flow
from A-to-B, for example, the A-to-B Enable (CEAB) input
must be LOW in order to enter data from the A Port or take
data from the B Port as indicated in the Data I/O Control
Table. With CEAB LOW, a LOW signal on (LEAB) input
makes the A-to-B latches transparent; a subsequent LOW-
to-HIGH transition of the LEAB line puts the A latches in
the storage mode and their outputs no longer change with
the A inputs. With CEAB and OEAB both LOW, the B out-
put buffers are active and reflect the data present on the
output of the A latches. Control of data flow from B-to-A is
similar, but using the CEBA, LEBA and OEBA.
