Overview
The SN65HVD10DR is a 3.3-V half-duplex RS-485 transceiver manufactured by Texas Instruments. This component combines a 3-state differential line driver and a differential input line receiver, designed for balanced transmission lines and compliant with ANSI standard TIA/EIA-485-A and ISO 8482:1993. It operates with a single 3.3-V power supply and is suitable for bidirectional data communication on multipoint bus-transmission lines. The device features active-high and active-low enables for direction control and offers low device standby supply current by disabling the driver and receiver.
