DESCRIPTION:

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

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.

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.

The FCT2543T is a non-inverting octal transceiver built using an

The FCT2543T has balanced output drive with current limiting resistors.
