Product Features  
Product Description  
• 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 PI74LPT16952 is a 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-B Enable (xCEAB) input must be LOW to enter data from xAx.  
ThedatapresentontheAportwillbeclockedontheBregisterwhen  
xCLKAB toggles from LOW-to-HIGH. The xOEAB control  
performs the output enable function on the B port. Control of data  
from B to A is similar, but uses the xCEAB, xCLKAB, and xOEAB  
inputs. By connecting the control pins of the two independent  
transceivers together, a full 16-bit operation can be achieved. The  
outputbuffersaredesignedwithaPower-Offdisableallowing“live  
insertion” of boards when used as backplane drivers.  
• 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  
• Multiple center pins and distributed Vcc/GND pins  
minimize switching noise
