Overview
The SN65LVDS31PWRG4 is a high-speed differential line driver produced by Texas Instruments. This device implements the electrical characteristics of low-voltage differential signaling (LVDS), which reduces power consumption, increases switching speeds, and allows operation with a 3.3-V supply rail. It is designed for both point-to-point and multidrop data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables. The SN65LVDS31PWRG4 is characterized for operation from –55°C to 125°C, making it suitable for defense, aerospace, and medical applications.
