PI74FCT646T/648T/651T/652T  
(25Ω Series PI74FCT2646T/2652T  
Fast CMOS Octal Registered Transceivers  
Product Description:  
ProductFeatures:  
Pericom Semiconductor’s PI74FCT series of logic circuits are  
produced in the Company’s advanced 0.6/0.8 micron CMOS  
technology, achieving industry leading speed grades. All  
PI74FCT2XXX devices have a built-in 25-ohm series resistor on  
all 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  
• Packagesavailable:

• Device models available upon request  
The PI74FCT646T/648T/651T/652T and PI74FCT2646T/2652T  
are designed with a bus transceiver with 3-state D-type flip-flops  
and control circuitry arranged for multiplexed transmission of data  
directlyfromthedatabusorfromtheinternalstorageregisters. The  
PI74FCT651/652T/2652TutilizeGABandGBAsignalstocontrol  
the transceiver functions. The PI74FCT646/2646T/648T utilize  
the enable control (G) and direction pins (DIR) to control the  
transceiver functions. SAB and SBA control pins are used to select  
either real-time or stored data transfer. The circuitry used for select  
control will eliminate the typical decoding glitch that occurs in a  
multiplexerduringthetransitionbetweenreal-timeandstoreddata.  
A low input level selects real-time data and a high selects stored  
data.  
The PI74FCT646T is a non-inverting option of the PI74FCT648T.  
The PI74FCT652T is a non-inverting option of the PI74FCT651T.
