DESCRIPTION:
The FCT2543T is a non-inverting octal transceiver 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 A0–A7 or to take data from B0–B7, 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.
FCT2543T parts are plug-in replacements for FCT543T parts.
