PI74FCT543/544/2543T Logic Block Diagram
Product Description
Pericom Semiconductors PI74FCT series of logic circuits are
produced using the Companys advanced 0.8 micron CMOS
technology, achieving industry leading speed grades. All
PI74FCT2XXX devices have a built-in 25 ohm series resistor on all
outputs to reduce noise because of reflections, thus eliminating the
need for an external terminating resistor.
The PI74FCT543T/544T and PI74FCT2543T is an 8-bit wide non-
inverting transceiver designed with 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 A0A7 or to take data from B0B7,
as indicated in the Truth Table. With CEAB LOW, a LOW signal
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 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 CEAB, LEAB, and OEAB inputs. The
PI74FCT543T is a non-inverting of the PI74FCT544T.
