The SN65HVD75DR with RS-485 Interface IC 3.3V-Supply RS-485 with IEC ESD Prot, manufactured by Texas Instruments is an integrated circuit designed for two-wire full-duplex communication in harsh environments. It is an industry-standard protocol and is designed to provide high-speed data transmission across long distances. It is suitable for point-to-point, multipoint applications. The device supports standard asynchronous data speeds up to 10 Mbps. It offers integrated protection against electrostatic discharges, reverse-voltage protection, and undervoltage lockout, and is designed for ±7-kV HBM ESD. The SN65HVD75DR has three interface pins, two for signal inputs (A and B) and one for enable control (RE/DE). It is rated to operate over an ambient temperature range of -40°C to +85°C.
