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 PI74FCT16823T, PI74FCT162823T and PI74FCT162H823
are 18-bit wide registers with clock enable (xCLKEN) and clear
(xCLR) controls that make these devices especially suitable for
parity bus interfacing in high-performance systems. The devices
can be operated as two 9-bit registers or one 18-bit register using the
control inputs. Signal pins are arranged in a flow-through
organization for ease of layout and hysteresis is designed into all
inputs to improve noise margin.
The PI74FCT16823T output buffers are designed with a Power-
Off disable function allowing “l(fā)ive insertion” of boards when the
devices are used as backplane drives.
The PI74FCT162823T 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 PI74FCT162H823T 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.
