Overview
The SN65LVDS179MDGKREP is a high-speed differential line driver and receiver produced by Texas Instruments. This device is designed to meet or exceed the requirements of the ANSI TIA/EIA-644-1995 standard for low-voltage differential signaling (LVDS). It operates from a single 3.3-V supply and is characterized for operation over a wide temperature range of –55°C to 125°C. The SN65LVDS179MDGKREP is suitable for point-to-point baseband data transmission over controlled impedance media such as printed circuit board traces, backplanes, or cables.
