PI74LPT240  
Fast CMOS 3.3V 8-Bit  
Inverting Buffer/Line Driver  
Product Features  
Product Description  
• CompatiblewithLCX™andLVT™familiesofproducts  
Pericom Semiconductor’s PI74LPT series of logic circuits are  
produced using the Company’s advanced 0.6 micron CMOS  
technology, achieving industry leading speed grades.  
• Supports 5V Tolerant Mixed-Signal Mode Operation  
– Input can be 3V or 5V  
– Output can be 3V or connected to 5V bus  
ThePI74LPT240isan8-bitinvertingbuffer/linedriverdesignedfor  
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.  
• Advanced Low-Power CMOSOperation  
• Excellentoutputdrivecapability:  
Balanced drives (24mA sink and source)  
• Low ground bounce outputs  
• Hysteresis on all inputs  
The PI74LPT240can 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  
• Packagesavailable:
