Overview
The SN65LVDS33MDREP is a high-speed differential receiver produced by Texas Instruments. This component is part of the SN65LVDS33-EP family, designed for point-to-point baseband data transmission over controlled impedance media such as printed-circuit board traces, backplanes, or cables. It operates with a single 3.3-V supply and is characterized for operation from –55°C to 125°C, making it suitable for a wide range of environmental conditions.
The device features an integrated failsafe circuit that prevents noise from being received as valid data under fault conditions such as disconnected cables, shorted lines, or powered-down transmitters. This enhances reliability in cabled and other connections where potentially damaging noise is a concern.
