说明

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 V_CC 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- line termination resistor.
