PI74AVC16835  
18-Bit Universal Bus Driver  
with 3-State Outputs  
ProductFeatures  
ProductDescription  
• Very high-speed, low-noise universal bus driver with  
embedded resistor outputs  
Pericom Semiconductor’s PI74AVC series of logic circuits  
are produced using the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.  
• Meets PC133 SDRAM Registered DIMM specification  
The18-bitPI74AVC16835universalbusdriverisdesigned for1.8V  
to3.6VVccoperation.  
• Implements output impedance control for low-noise and  
heavy-load applications  
• Fast Propagation Delay:  
2.5ns max. for 50pF test load  
DataflowfromAtoYiscontrolledbyOutputEnable(OE).Thedevice  
operates in the transparent mode when LE is HIGH. The A data is  
latched if CLK is held at a high or low logic level. If LE is LOW, the  
A-busisstoredinthelatch/flip-floponthelow-to-hightransitionof  
CLK.WhenOEisHIGH,theoutputsareinthehigh-impedancestate.  
• VCC = 3.3V or 2.5V or 1.8V  
• Packages available:  
–56-pin240milwideplasticTSSOP(A)  
–56-pin173milwideplasticTVSOP(K)  
The PI74AVC16835 bus driver is designed to drive an array of 133  
MHz synchronous memory chips, with minimal undershoot/  
overshootnoise,andtomeettheinputsignalrise/falltimerequirement  
of memory chips.  
Theoutputdriversofthisparthaveanembeddedseries-resistor.For  
DIMM module design, no external series termination resistors near  
thebufferdriversoranyotherterminationresistorsarerequired.This  
feature simplifies DIMM module layout design, and results in cost  
savings.
