Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are
produced in the Company’s 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 A0–A7 or to take
data from B0–B7, 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.
