Overview
The SN65LVDT390PWR is a high-speed differential line receiver produced by Texas Instruments. This component is part of a family of 4-, 8-, or 16-channel differential line receivers that implement the electrical characteristics of low-voltage differential signaling (LVDS). LVDS technology reduces power consumption, increases switching speeds, and allows operation with a 3.3-V supply rail. The SN65LVDT390PWR is specifically designed for point-to-point baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables.
