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 PI74FCT16827T, PI74FCT162827T, and PI74FCT162H827T are
20-bit wide bus drivers designed to provide buffering and high-
performance bus interfacing for wide data/address paths or buses
with parity. Two pair of nanded output enable controls allow the
devices to be operated as two 10-bit buffers or as one 20-bit buffer.
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 PI74FCT16827T output buffers are designed with a Power-Off
disable function allowing “live insertion” of boards when the
devices are used as backplane drives.
The PI74FCT162827T 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 PI74FCT162H827T 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.
