Overview
The SN65LVDS348PWR is a high-speed, quadruple differential receiver produced by Texas Instruments. This component is designed to operate within a wide common-mode input voltage range, making it suitable for receiving TIA/EIA-644 signals with up to 3-V of ground noise or various differential and single-ended logic levels. The device is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) to match the industry-standard footprint of the DS90LV048. It features a flow-through architecture, which simplifies board layout and reduces crosstalk between receivers.
