PI74AVC16834

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 PI74AVC16834 universal bus driver is designed for

1.8V to 3.6V V_CCoperation.

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 LOW. The A

data is latched if CLK is held at a high or low logic level. If LE is

HIGH, 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.

V_CC= 3.3V or 2.5V or 1.8V

Packages available:

56-pin240milwideplasticTSSOP(A)

56-pin173milwideplasticTVSOP(K)

The PI74AVC16834 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

GND

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.
