Overview
The SN65LVDS31PWR 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. The SN65LVDS31PWR is part of a family of devices that include the SN55LVDS31, SN65LVDS3487, and SN65LVDS9638, all of which are designed for high-speed data transmission over controlled impedance media such as printed-circuit board traces, backplanes, or cables.
