ProductFeatures  
ProductDescription  
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.  
• PI74FCT240/241/244/540/541TandPI74FCT2240/2241/2244/  
2541T are pin compatible with bipolar FAST™ Series at a  
higher speed and lower power consumption  
• 25series 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  
The PI74FCT240T/241T/244T/540T/541T and P174FCT2240T/  
2241T/2244/2541T are 8-bit wide driver circuits, designed to be  
used in applications requiring high-speed and high-output drive.  
Ideal applications would include bus drivers, memory drivers,  
address drivers, and system clock drivers.  
• Packagesavailable:  
– 20-pin173milwideplasticTSSOP(L)  
– 20-pin209milwideplasticSSOP(H)  
– 20-pin300milwideplasticDIP(P)  
– 20-pin150milwideplasticQSOP(Q)  
– 20-pin150milwideplasticTQSOP(R)  
– 20-pin300milwideplasticSOIC(S)  
• Device models available upon request  
The PI74FCT540T and PI74FCT541/2541T provide similar driver  
capabilities, but have their pins physically grouped by function.  
All inputs are located on one side of the package, while outputs are  
on the opposite side, allowing for a much simpler and denser board  
layout.
