Functional Description
The LCX16543 contains sixteen non-inverting transceivers
with 3-STATE outputs. The device is byte controlled with
each byte functioning identically, but independent of the
other. The control pins may be shorted together to obtain
full 16-bit operation. The following description applies to
each byte. For data flow from A to B, for example, the
A-to-B Enable (CEABn) input must be LOW in order to
enter data from A0–A15 or take data from B0–B15, as indi-
cated in the Data I/O Control Table. With CEABn LOW, a
LOW signal on the A-to-B Latch Enable (LEABn) input
makes the A-to-B latches transparent; a subsequent LOW-
to-HIGH transition of the LEABn signal puts the A latches in
the storage mode and their outputs no longer change with
the A inputs. With CEABn and OEABn 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 CEBAn, LEBAn and
OEBAn inputs.
