Overview
The SN75HVD10DR, produced by Texas Instruments, is a 3.3-V RS-485 transceiver designed for balanced transmission lines. This monolithic integrated circuit combines a 3-state differential line driver and a differential input line receiver, operating with a single 3.3-V power supply. It meets or exceeds the requirements of ANSI standard TIA/EIA-485-A and ISO 8482:1993, making it suitable for bidirectional data communication on multipoint bus-transmission lines.
