The IDT54/74FCT543/A/C is a non-inverting octal trans-

ceiver built using an advanced dual metal CMOS technology.

These devices contain 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

–A

or to take data from

–B

, 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.
