For most RS-485 sensor networks, actuator links, and Modbus RTU applications running at 9600 or 19200 baud, this part has headroom. If your design requires 1 Mbps or higher, this transceiver will not meet the timing budget; look at the SN65HVD17xx family for faster rates. If your system runs on 3.3 V logic, this part needs a level translator or a separate 5 V supply — it is not a 3.3 V device. For volume planning, the base product number 65HVD1785 covers multiple package and tape/reel variants, so alternate orderable options exist within the same die.","metaTitle":"SN65HVD1785DG4 RS-485 Transceiver, Half-Duplex, 115 Kbps","metaDescription":"Texas Instruments SN65HVD1785DG4 half-duplex RS-422/RS-485 transceiver. 115 Kbps data rate, 4.5V–5.5V supply, 50 mV hysteresis, -40°C to 105°C.","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":"4.5V ~ 5.5V","Base Product Number":"65HVD1785","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~105°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b38d061c4360ce75c40342dad0f5f015.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1785DG4/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD1785DG4 a drop-in replacement for SN65HVD1785D?","answer":"Yes, the SN65HVD1785DG4 is a direct drop-in replacement for the SN65HVD1785D. Both share the same 8-SOIC footprint, pinout, and electrical specifications. The 'G4' suffix indicates RoHS-compliant green packaging, while the older 'D' suffix may be non-green. No board layout or BOM changes are required to swap them."},{"question":"Can SN65HVD1785DG4 be used with a 5V Arduino?","answer":"Yes. Connect the driver and receiver enable pins to digital outputs for half-duplex control. The 115 Kbps data rate is sufficient for typical UART communication at 9600 or 115200 baud."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD1785DG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD1785DG4 when reusing this data.
