SN65LVDS349 Quad High-Speed Differential Receiver Texas Instruments SN65LVDS349 Quad High-Speed Differential Receiver features a wide common-mode input voltage range. This allows receipt of TIA/EIA-644 signals with up to 3V of ground noise or a variety of differential and single-ended logic levels. The TI SN65LVDS349 is in a 16-pin package and 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 TI LVDS349 receiver provides three times the standard minimum common-mode noise voltage tolerance.
