At 400 kbps, the practical cable length on a typical RS-485 segment is around 4000 feet (1200 meters) before signal degradation sets in, assuming proper termination. The 70 mV hysteresis on the receiver input rejects common-mode noise that couples onto the pair in a motor-drive or PLC environment.","metaTitle":"SN65HVD71DGKR RS422/RS485 Full-Duplex Transceiver, 400 kbps","metaDescription":"Texas Instruments SN65HVD71DGKR RS422/RS485 full-duplex transceiver in 8-VSSOP. 400 kbps data rate, 70 mV hysteresis, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"400kbps","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD71","Receiver Hysteresis":"70 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-VSSOP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9087c32540c5c64471c20d05147d7cee.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD71DGKR/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD71DGKR equivalent to SN65HVD72?","answer":"The SN65HVD72 is a half-duplex transceiver, while the SN65HVD71DGKR is full-duplex.
