Full duplex means separate twisted pairs for transmit and receive, so the bus can sustain continuous back-to-back throughput without direction switching — critical for encoder feedback or high-speed data concentrators. The 50 mV hysteresis filters out reflections on unterminated stubs, giving the layout engineer some margin on stub length. ## 3.3 V supply and industrial temperature — rail and environment fit The 14-SOIC footprint is a standard narrow-body (3.90 mm width), compatible with most automated assembly lines.","metaTitle":"TI SN65HVD33D RS-485/RS-422 Transceiver, Full Duplex","metaDescription":"Texas Instruments SN65HVD33D full-duplex RS-485/RS-422 transceiver with 23 Mbps data rate, 3V to 3.6V supply, 50 mV hysteresis, -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)","Product Status":"Active","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":"$5.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b478029e1adc17f2a0ac5127fa8c6674.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD33D/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65HVD33D and SN65HVD32D?","answer":"The SN65HVD33D is a full-duplex transceiver, while the SN65HVD32D is half-duplex. Both operate at 23 Mbps and share the same 3.3 V supply and 14-SOIC package, but the full-duplex SN65HVD33D uses separate transmit and receive pairs, eliminating bus-turnaround dead cycles. If your protocol requires simultaneous send/receive or you need to avoid direction switching overhead, the SN65HVD33D is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD33D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD33D when reusing this data.
