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.
