Functional Description
The ACTQ16543 contains sixteen non-inverting transceiv-
ers 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 exam-
ple, the A-to-B Enable (CEAB
n
) input must be LOW in
order to enter data from A
0
–A
15
or take data from B
0
–B

,
as indicated in the Data I/O Control Table. With CEAB
n
LOW, a LOW signal on the A-to-B Latch Enable (LEAB
n
)
input makes the A-to-B latches transparent; a subsequent
LOW-to-HIGH transition of the LEAB
n
signal puts the A
latches in the storage mode and their outputs no longer
change with the A inputs. With CEAB
n
and OEAB
n
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
n
,
LEBA
n
and OEBA
n
inputs.
