DESCRIPTION:
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
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 FCT543 is a non-inverting octal transceiver built using an advanced
