Logic Block Diagram
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 PI74FCT162Q244T is a non-inverting 16-bit buffer/line driver
designed for bus interface applications where low noise operation
is essential.
The PI74FCT162Q244T is designed with current limiting resistors
at its outputs to control the output edge rate resulting in lower
ground bounce and undershoot. This device features a typical
output impedance of 35Ω, eliminating the need for external
terminating resistors for most bus interface applications. This noise
suppression benefit is designated by the letter “Q” (for quiet) in the
part number.
The PI74FCT162Q244T also features “Bus Hold” which retains
the input’s last state whenever the input goes to high-impedance
preventing “floating” inputs and eliminating the need for pullup/
down resistors.
This high-speed, low power device also features a flow-through
organization for ease of board layout. These devices are designed
with three-state controls to operate in a Quad-Nibble, Dual-Byte, or
a single 16-bit word mode.
