Overview
The SN65LVDS9638DGKG4 is a high-speed differential line driver produced by Texas Instruments. This device is part of the SNx5LVDSxx family, which implements the electrical characteristics of low-voltage differential signaling (LVDS) as specified by the ANSI TIA/EIA-644A standard. It operates from a single 3.3-V supply and is designed to drive 100-Ω transmission lines, making it suitable for high-speed data transmission applications.
The device features dual-channel operation, with each channel capable of delivering differential output signals with a nominal magnitude of 340 mV. It is characterized by low power consumption, high switching speeds, and robust ESD protection, making it ideal for various high-reliability and high-speed applications.
