PI74FCT646T/648T/651T/652T

(25Ω Series PI74FCT2646T/2652T

Fast CMOS Octal Registered Transceivers

ProductDescription

ProductFeatures

Pericom Semiconductors PI74FCT series of logic circuits are

produced using the Companys advanced 0.6/0.8 micron CMOS

technology, achieving industry leading speed grades. All

PI74FCT2XXXdeviceshaveabuilt-in25-ohmseriesresistoronall

outputs to reduce noise because of reflections, thus eliminating the

need for an external terminating resistor.

PI74FCT646T/648T/651T/652T/2646T/2652Tispincompatible

with bipolar FAST Series at a higher speed and lower power

consumption

25Ω series resistor on all outputs (FCT2XXX only)

TTL input and output levels

Low ground bounce outputs

Extremelylowstaticpower

Hysteresis on all inputs

Industrial operating temperature range: 40°C to +85°C

ThePI74FCT646T/648T/651T/652TandPI74FCT2646T/2652Tare

designed with a bus transceiver with 3-state D-type flip-flops and

control circuitry arranged for multiplexed transmission of data

directly from the data bus or from the internal storage registers. The

control (G) and direction pins (DIR) to control the transceiver

eliminate the typical decoding glitch that occurs in a multiplexer

duringthetransitionbetweenreal-timeandstoreddata. Alowinput

level selects real-time data and a high selects stored data.

The PI74FCT646T is a non-inverting option of the PI74FCT648T.
