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 PI74FCT16952T, PI74FCT162952T, and PI74FCT162H952T
are 16-bit registered 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. The
data present on the A port will be clocked on the B register when
xCLKAB toggles from LOW-to-HIGH. The xOEAB control
performs the output enable function on the B port. Control of data
from B to A is similar, but uses the xCEBA, xCLKBA, and xOEBA
inputs. By connecting the control pins of the two independent
transceivers together, a full 16-bit operation can be achieved. The
output buffers are designed with a Power-Off disable allowing
“live insertion” of boards when used as backplane drivers.
The PI74FCT16952T output buffers are designed with a Power-
Off disable function allowing “live insertion” of boards when used
as backplane drivers.
The PI74FCT162952T 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 PI74FCT162H952T 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.
