PI74AVC16834

18-Bit Universal Bus Driver

with 3-State Outputs

Product Features

• Very high-speed, low-noise universal bus driver with

embedded resistor outputs

• Meets PC133 SDRAM Registered DIMM specification

• Implements output impedance control for low-noise and

heavy-load applications

• Fast Propagation Delay:

2.5ns max. for 50pF test load

• V

= 3.3V or 2.5V or 1.8V

• Packaging (Pb-free & Green available):

– 56-pin 240 mil wide plastic TSSOP (A)

Product Description

The 18-bit PI74AVC16834 universal bus driver is designed for 1.8V

to 3.6V V

operation.

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.

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.

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.

Notes:

Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at these or any other conditions above those

indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

1. Input and output negative voltage ratings may be exceeded if the input and output current ratings are observed.

2. Output positive voltage rating may be exceeded up to 4.6V maximum if the output current rating is observed.

3. Package thermal impedance is calculated in accordance with JESD 51.
