The packaging (8-SOIC) is standard, but the die and assembly are rated for that extended range. The part is not 5V-tolerant on the supply, so if the rest of the system runs at 5V, a level translator is required on the digital I/O lines. The driver and receiver pins are referenced to VCC, so logic input thresholds scale with the supply. ## Half-duplex bus topology As a half-duplex device, the SN65HVD11HD uses a single pair of differential bus lines for both transmit and receive. The driver enable pin (DE) controls which direction the bus is driven. For full-duplex operation requiring simultaneous send and receive, a second part or a different transceiver would be needed.","metaTitle":"SN65HVD11HD RS-485/RS-422 Transceiver, 10 Mbps","metaDescription":"Texas Instruments SN65HVD11HD half-duplex RS-485/RS-422 transceiver, 10 Mbps data rate, 3V-3.6V supply, -55°C to 175°C operating range, 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":"Half","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"10Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD11","Receiver Hysteresis":"41 mV","Operating Temperature":"-55°C~175°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$130.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3ec9d8659df024d92accc6a8e2019aa0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD11HD/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD11HD compatible with 5V logic?","answer":"The logic I/O thresholds are referenced to VCC, so 5V logic levels are not directly compatible.
