Functional Description
The ACQ/ACTQ544 contains two sets of eight D-type
latches, with separate input and output controls for each
set. 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 A

, as indicated in the
Data I/O Control Table. With CEAB LOW, a LOW signal on
the A-to-B Latch Enable (LEAB) input makes the A-to-B
latches transparent; a subsequent LOW-to-HIGH transition
of the LEAB signal 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 3-STATE B output buffers
are active and reflect the data present at the output of the A
latches. Control of data flow from B to A is similar, but using
the CEBA, LEBA and OEBA inputs.
