The 50 mV receiver hysteresis filters noise on long cable runs — a practical margin for industrial backplanes where ground differentials and reflections degrade the signal edge. ## Supply and temperature range for industrial environments Surface-mount 8-SOIC (0.154\" width, 3.90 mm body) footprint matches a common PCB land pattern; the tube packaging suits low-to-mid volume assembly without reel fees. ## Active lifecycle and sourcing posture No official successor has been published; the base product number 65HVD179 shares the same die family as the SN65HVD178 series, but the '179 is a full-duplex variant while the '178 is half-duplex — a direct drop-in replacement is not pin-compatible without a board change.","metaTitle":"TI SN65HVD179DG4 RS-485/RS-422 Transceiver, 25 Mbps","metaDescription":"Texas Instruments SN65HVD179DG4 RS-485/RS-422 full-duplex transceiver, 25 Mbps data rate, 50 mV hysteresis, 4.5-5.5V, -40 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":"4.5V ~ 5.5V","Base Product Number":"65HVD179","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/98d09a458d6a43a76d916da4350d3788.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD179DG4/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of the SN65HVD179DG4?","answer":"The SN65HVD179DG4 supports a data rate of 25 Mbps, suitable for high-speed RS-485/RS-422 links such as PROFIBUS or industrial Ethernet backplanes."},{"question":"Is the SN65HVD179DG4 full duplex?","answer":"Yes, it is a full-duplex transceiver with separate driver and receiver channels, allowing simultaneous transmit and receive on a four-wire bus."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD179DG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD179DG4 when reusing this data.
