PI74LPT16244  
3.3V, 16-Bit Buffer/Line Driver  
Features  
Description  
• Compatible with LCX and LVT families of products  
Pericom Semiconductor’s PI74LPT16244 is a 16-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 reections and lower EMI and  
RFI effects. This makes it ideal for driving on-board buses and  
transmission lines. This device is designed with three-state  
controls to operate in a Quad-Nibble, Dual-Byte, or a single  
16-bit word mode.  
• Supports 5V Tolerant Mixed Signal Mode Operation  
– Input can be 3V or 5V  
– Output can be 3V or connected to 5V bus  
• Advanced Low Power CMOS Operation  
• Excellent output drive capability:  
Balanced drives (24mA sink and source)  
• Pin compatible with industry standard double-density pinouts  
• Low ground bounce outputs  
The PI74LPT16244 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.  
• Hysteresis on all inputs  
• Industrial operating temperature range: –40°C to +85°C  
• Multiple center pins and distributed Vcc/GND pins minimize  
switching noise  
• Packaging (Pb-free & Green available):  
– 48-pin 240-mil wide thin plastic TSSOP (A)  
– 48-pin 300-mil wide plastic SSOP (V)
