At this rate the part suits high-throughput links like motor-drive feedback, multi-axis encoder networks, or daisy-chained sensor arrays where the bus must keep up with real-time control loops. Full-duplex operation means simultaneous transmit and receive over two twisted pairs — no direction-toggle overhead. ## Supply rail and temperature range — where it sits on the board The 14-SOIC footprint is a common, rework-friendly package. No exposed pad to route, no thermal-via pattern to design — just the usual SOIC-14 land pattern and a 0.1 µF decoupling cap close to the supply pin. TI lists the SN65HVD33DG4 as Active. For a BOM line this means the part stays in the supply channel for new-production builds without the date-code anxiety that comes with discontinued interface parts. The 14-SOIC variant (DG4 suffix) is the standard surface-mount option — no oddball reel or tray quantity to complicate procurement.","metaTitle":"TI SN65HVD33DG4 RS-485/RS-422 Transceiver, 23 Mbps","metaDescription":"Texas Instruments SN65HVD33DG4 full-duplex RS-485/RS-422 transceiver. 23 Mbps data rate, 50 mV receiver hysteresis, 3V–3.6V supply, -40°C to 85°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":"Tube","Protocol":"RS422, RS485","Data Rate":"23Mbps","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD33","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b478029e1adc17f2a0ac5127fa8c6674.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD33DG4/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of SN65HVD33DG4?","answer":"23 Mbps, full duplex. That's the differential bus rate; the UART-side logic runs at the same bit clock."},{"question":"What is the closest pin-compatible alternative to SN65HVD33DG4?","answer":"Within the 65HVD33 family the pinout is consistent across the SOIC-14 variants — the difference is typically in the data-rate grade or temperature range. The SN65HVD33DG4 is the 23 Mbps, industrial-temperature version. A lower-speed sibling like the SN65HVD33D (which runs at lower data rates) shares the same footprint and supply range, so a BOM swap is a board-layout match if the throughput requirement changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD33DG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD33DG4 when reusing this data.
