PI74FCT3244  
Fast CMOS 3.3V 8-Bit  
Buffer/Line Driver  
Features  
Description  
• Advanced Low Power CMOS operation  
• Compatible with LVC class of products  
• Compatible with industry standard octal pinouts  
Pericom Semiconductor’s PI74FCT3 series of logic circuits are  
producedintheCompany’sadvanced0.6micronCMOStechnology,  
achieving industry leading speed grades.  
• Excellent output drive capability:  
The PI74FCT3244 is an 8-bit buffer/line driver designed for  
driving high capacitive memory loads. With its balanced-drive  
characteristics, this high-speed, low power device provides lower  
ground bounce, transmission line matching of signals, fewer line  
reflections and lower EMI and RFI effects. This makes it ideal for  
driving on-board buses and transmission lines.  
Balanced Drives (24mA sink and source)  
• Can serve as a 5V to 3V translator  
• Inputs can be driven by 3.3 V or 5V devices  
• Low ground bounce outputs  
• Hysteresis on all inputs  
The PI74FCT3244 can be driven from either 3.3V or 5.0V  
devices allowing this device to be used as a translator in a mixed  
3.3/5.0V system.  
• Industrial operating temperature range:  
–40°C to +85°C  
• Packaging:  
– 20-pin 173-mil wide plastic TSSOP (L)  
– 20-pin 150-mil wide plastic QSOP (Q)  
– 20-pin 300-mil wide plastic SOIC (S)
