Functional Description
The LVT16543 and LVTH16543 contain 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 sub-
sequent 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 output 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. Each byte has separate control inputs, allowing the
device to be used as two 8-bit transceivers or as one 16-bit
transceiver.
