At 115 kbps the driver slew rate is controlled enough to keep radiated emissions low over unshielded twisted pair up to a few hundred metres. This is the sweet spot for Modbus RTU, BACnet MS/TP, and similar polled protocols. If your application needs to push past 1 Mbps — for example, daisy-chaining servo drives with position updates — this part will not get you there; you would step up to the SN65HVD1781 or a 10 Mbps variant in the same family. The wide supply tolerance means the same BOM line can serve a 3.3 V design and a 5 V design without a separate regulator or level shifter. The 50 mV receiver hysteresis cleans up noise on long cable runs where ground potential difference can reach a few volts. Both driver and receiver are active from the same rail, so there is no separate VIO pin to route. For a dual-sourcing strategy, the SN65HVD1781DG4 is a pin-compatible sibling in the same SOIC-8 footprint — the main difference is a higher data rate (1 Mbps vs 115 kbps), so verify your bus timing margin before substituting.","metaTitle":"SN65HVD1780DG4 RS-485 Transceiver, 115 kbps, SOIC-8","metaDescription":"TI SN65HVD1780DG4 half-duplex RS-422/RS-485 transceiver, 3.15 V to 5.5 V supply, 115 kbps data rate, 50 mV hysteresis, SOIC-8, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"115Kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 5.5V","Base Product Number":"65HVD1780","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.7500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/841cd41992f84285f75bf28fceb4b47c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1780DG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65HVD1780DG4 and SN65HVD1781DG4?","answer":"The SN65HVD1781DG4 supports a higher data rate of 1 Mbps versus the 115 kbps of the SN65HVD1780DG4.
