PI74AVC16835  
18-Bit Universal Bus Driver  
with 3-State Outputs  
Product Features  
Product Description  
• 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  
The 18-bit PI74AVC16835 universal bus driver is designed for  
1.8V to 3.6V Vcc operation.  
• Implements output impedance control for low-noise and  
heavy-load applications  
• Fast Propagation Delay:  
2.5ns max. for 50pF test load  
Data flow from A to Y is controlled by Output Enable (OE). The  
device 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-bus is stored in the latch/flip-flop on the low-to-high  
transition of CLK. When OE is HIGH, the outputs are in the high-  
impedance state.  
• 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/  
overshoot noise, and to meet the input signal rise/fall time  
requirement of memory chips.  
Product Pin Configuration  
The output drivers of this part have an embedded series-resistor.  
For DIMM module design, no external series termination resistors  
near the buffer drivers or any other termination resistors are  
required. This feature simplifies DIMM module layout design, and  
results in cost savings.
