DESCRIPTION

Active Failsafe Assures a High-level Output
When an Input Signal Is not Present
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

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-Ω line termination resistor.
