At that rate on a properly terminated 120 Ω twisted pair, the usable cable length drops to roughly 50 meters or less — the classic speed-versus-distance trade-off. If your bus runs shorter runs at lower baud, the part still works fine; the 50 mV receiver hysteresis cleans up noise on slow edges without external filtering. ## 3.3 V supply only — not a 5 V tolerant bus part The bus pins are not 5 V tolerant; feeding a 5 V logic signal into the driver input or pulling the bus above the absolute maximum will damage the transceiver. If your system runs mixed 3.3 V / 5 V logic, add a level translator or pick a 5 V-capable RS485 part like the SN65HVD3082E. ## Industrial temperature range, active lifecycle It is RoHS-compliant and lead-free per the DG4 suffix.","metaTitle":"SN65HVD379DG4 RS422/RS485 Transceiver, Full Duplex, 25 Mbps","metaDescription":"Texas Instruments SN65HVD379DG4 full-duplex RS422/RS485 transceiver, 25 Mbps data rate, 3 V to 3.6 V supply, -40°C to 85°C, 8-SOIC.","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":"Tube","Protocol":"RS422, RS485","Data Rate":"25Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD379","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$58.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f519fb0aa88f4dddd21ceda573c71239.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD379DG4/alternatives.json"},"ai":{"faq":[{"question":"Can SN65HVD379DG4 replace SN65HVD379D?","answer":"Yes — the SN65HVD379DG4 is the lead-free, RoHS-compliant version of the SN65HVD379D.
