PI74LPT162Q952  
Fast CMOS 3.3V  
16-Bit Registered Transceivers  
ProductFeatures  
ProductDescription  
• CompatiblewithLCX™andLVT™familiesofproducts  
Pericom Semiconductor’s PI74LPT series of logic circuits are  
producedintheCompany’sadvanced0.6micronCMOStechnology,  
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  
The PI74LPT162Q952 has 16-bit registered transceivers organized  
with two sets of eight D-type latches with separate input and output  
controls for each set. For data flow from A to B, for example, the  
A-to-BEnable(xCEAB)inputmustbeLOWtoenterdatafromxAx.  
ThedatapresentontheAportwillbeclockedontheBregisterwhen  
xCLKABtogglesfromLOW-to-HIGH.ThexOEABcontrolperforms  
the output enable function on the B port. Control of data from B to  
Aissimilar, butusesthexCEAB, xCLKAB, andxOEABinputs. By  
connecting the control pins of the two independent transceivers  
together, a full 16-bit operation can be achieved. The output buffers  
are designed with a Power-Off disable allowing “live insertion” of  
boards when used as backplane drivers.  
• Advanced Low Power CMOS Operation  
• Excellentoutputdrivecapability:  
Balanced drives (12mA sink and source)  
• 25-Ohm Series resistor on outputs to reduce  
overshoot and undershoot  
• 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  
ThePI74LPT162Q952canbedrivenfromeither3.3Vor5.0Vdevices  
allowing this device to be used as a translator in a mixed  
3.3/5.0Vsystem.  
• Multiple center pins and distributed Vcc/GND pins
