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 PI74FCT162Q245T is a 16-bit bidirectional transceiver designed
for asynchronous two-way communication between data buses.
The direction control input pin (xDIR) determines the direction of
data flow through the bidirectional transceiver. The Direction and
Output Enable controls are designed to operate these devices as
either two independent 8-bit transceivers or one 16-bit transceiver.
The output enable (OE) input, when HIGH, disables both A and B
ports by placing them in HIGH Z condition.
The PI74FCT162Q245T 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 35
, 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 PI74FCT162Q245T 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.
