DESCRIPTION

The SN65LVDS349 is a high-speed, quadruple

differential receiver with a wide common-mode input

voltage range. This allows receipt of TIA/EIA-644

signals with up to 3-V of ground noise or a variety of differential and single-ended logic levels. The '349 is

in a 16-pin package to match the industry-standard

footprint of the DS90LV048. The '349 offers a

flow-through architecture with all inputs on one side

and outputs on the other to ease board layout and

reduce crosstalk between receivers.

The LVDS349 provides 3x the standard's minimum

common-mode noise voltage tolerance. The -4 V to

5 V common-mode range allows usage in harsh

operating environments or accepts LVPECL, PECL,

LVECL, ECL, CMOS, and LVCMOS levels without

level shifting circuitry. See the Application Information

Section for more details on the ECL/PECL to LVDS

interface.
