Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced in the Company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74FCT16543T, PI74FCT162543T and PI74FCT162H543T are 16-
bit latched transceivers organized 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
(xCEAB) input must be LOW in order to enter data from xAx or to
take data from xBx, as indicated in the Truth Table. With xCEAB
LOW, a LOW signal makes the A-to-B latches transparent; a
subsequent LOW-to-HIGH transition of the xLEAB signal puts the
A latches in the storage mode and their outputs no longer change the
A inputs. With xCEAB and xOEAB 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 xCEBA,
xLEBA, and xOEBA inputs.
The PI74FCT16543T output buffers are designed with a Power-Off
disable allowing “live insertion”of boards when used as backplane
drivers.
The PI74FCT162543T has ±24 mA balanced output drivers. It is
designed with current limiting resistors at its outputs to control the
output edge rate resulting in lower ground bounce and undershoot.
This eliminates the need for external terminating resistors for most
interface applications.
The PI74FCT162H543T has “Bus Hold” which retains the input’s
last state whenever the input goes to high-impedance preventing
“floating” inputs and eliminating the need for pull-up/down
resistors.
