Overview
The SN65LVDS34DR is a quad Low-Voltage Differential Signaling (LVDS) receiver produced by Texas Instruments. This component is part of a family of high-speed differential receivers that offer the widest common-mode input voltage range in the industry. It is designed for point-to-point baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables. The device operates with a single 3.3-V supply and is characterized for operation from -40°C to 85°C, making it suitable for a wide range of applications requiring high-speed data transfer and robust noise tolerance.
