Overview
The SN65LVDS33DR is a quad Low-Voltage Differential Signaling (LVDS) receiver produced by Texas Instruments. This component is part of a family of LVDS data line receivers known for their wide common-mode input voltage range and high-speed signaling capabilities. The SN65LVDS33DR operates with a single 3.3-V supply and is designed for point-to-point baseband data transmission over controlled impedance media such as printed-circuit board traces, backplanes, or cables.
