At 50 Mbps, this transceiver supports high-speed serial links where the bus clocks at tens of megahertz, enabling fast sensor polling, actuator control, and data acquisition over twisted-pair cabling. Full-duplex operation means simultaneous transmit and receive on separate pairs, doubling effective throughput compared to half-duplex in the same clock cycle.","metaTitle":"SN65HVD1477D RS-485/RS-422 Transceiver, 50 Mbps, 3.3V","metaDescription":"Texas Instruments SN65HVD1477D full-duplex RS-485/RS-422 transceiver, 50 Mbps data rate, 3V-3.6V supply, -40°C to 125°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":"50Mbps","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":"65HVD1477","Receiver Hysteresis":"70 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1b77e1f02f3e6aa653cf272a9e3beb9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1477D/alternatives.json"},"ai":{"faq":[{"question":"Can SN65HVD1477D replace SN65HVD1476D?","answer":"The SN65HVD1477D is a full-duplex transceiver like the SN65HVD1476D, both from the same 65HVD147x family, but the 1477D is rated for 50 Mbps versus the 1476D's lower data rate.
