Fast CMOS 3.3V 16-Bit Registered Transceivers  
Product Features  
• CompatiblewithLCXandLVTfamiliesofproducts  
Product Description  
Pericom Semiconductor’s PI74LPT series of logic circuits are pro-  
duced in 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  
3
– Output can be 3V or connected to 5V bus  
The PI74LPT16646 is a 16-bit registered transceiver organized as  
two independent 8-bit bus transceivers designed with 3-state  
D-type flip-flops and control circuitry arranged for multiplexed  
transmission of data directly from the data bus or from the internal  
storage registers. Each 8-bit transceiver utilizes the enable control  
(xOE)anddirectionpins(xDIR)tocontrolthetransceiverfunctions.  
The Select (xSAB and xSBA) control pins are used to select either  
real-timeorstoreddatatransfer.Thecircuitryusedforselectcontrol  
willeliminatethetypicaldecodingglitchthatoccursinamultiplexer  
duringthetransitionbetweenreal-timeandstoreddata. Alowinput  
level selects real-time data and a high selects stored data.  
• Advanced Low Power CMOS Operation  
• Excellent output drive capability:  
Balanced drives (24 mA sink and source)

• Pin compatible with industry standard double-density  
pinouts  
• Low ground bounce outputs  
• Hysteresis on all inputs  
• Industrial operating temperature range: –40°C to +85°C

allowing this device to be used as a translator in a mixed  
3.3/5.0V system.  
• Multiple center pins and distributed Vcc/GND pins
