Powered from 3V to 3.6V, this part is sized for a 3.3V nominal supply. The bus pins are RS-485 compliant, so the differential bus levels are not 5V CMOS — they follow the RS-485 standard. The receiver outputs are 3.3V logic levels. If the host UART runs at 5V, a level translator between the transceiver and the controller is needed. It is not AEC-Q100 qualified, so automotive under-hood or cabin applications would need a different grade.","metaTitle":"TI SN65HVD34DG4 RS-485/RS-422 Transceiver, 5 Mbps","metaDescription":"Texas Instruments SN65HVD34DG4 RS-485/RS-422 transceiver, 5 Mbps full-duplex, 3V-3.6V supply, 14-SOIC, -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":"5Mbps","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":"65HVD34","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":"$58.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b478029e1adc17f2a0ac5127fa8c6674.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD34DG4/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of SN65HVD34DG4?","answer":"The data rate is 5 Mbps, which covers most RS-485 industrial fieldbus applications."},{"question":"Is SN65HVD34DG4 compatible with 5V logic?","answer":"The receiver outputs are 3.3V logic levels.
