DESCRIPTION:
The FCT543T/FCT2543T is a non-inverting octal trans-
ceiver built using an advanced dual metal CMOS technology.
This device 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
0
–A
7
or to take data from
B
0
–B
7
, as indicated in the Function 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 from B to A is similar, but uses the
CEBA
,
LEBA
and
OEBA
inputs.
The FCT2543T has balanced output drive with current
limiting resistors. This offers low ground bounce, minimal
undershoot and controlled output fall times-reducing the need
for external series terminating resistors. FCT2xxxT parts are
plug-in replacements for FCTxxxT parts.
