Overview
The SN65MLVD204AD is a multipoint low-voltage differential (M-LVDS) line driver and receiver produced by Texas Instruments. This device is optimized for signaling rates up to 100 Mbps and complies with the M-LVDS standard TIA/EIA-899. It is designed to enhance signal integrity through controlled slew rate on the driver output, minimizing reflections from unterminated stubs. The device also features 8-kV ESD protection on the bus pins, ensuring robustness. It operates over a temperature range of –40°C to 85°C, making it suitable for various industrial and communication applications.
