DESCRIPTION

The SN65LVDS348, SN65LVDT348,

SN65LVDS352, and SN65LVDT352 are high-speed,

quadruple differential receivers 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 '348 is in a 16-pin

package to match the industry-standard footprint of

the DS90LV048. The '352 adds two additional VCC

and GND pins in a 24-pin package to provide higher

data transfer rates with multiple receivers in

operation. All offer a flow-through architecture with all

inputs on one side and outputs on the other to ease

board layout and reduce crosstalk between

receivers. LVDT versions of both integrate a 110-W

line termination resistor.

These receivers also provide 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.
