The 115 kbps data rate is deliberate: this is a robust, noise-immune bus part for long cable runs and high common-mode voltages, not a high-speed link. The 50 mV receiver hysteresis cleans up a noisy bus, so the receiver doesn't chatter when the line idles or sees slow edges. ## Supply range and bus compatibility That means you can run it on a 3.3 V rail and still get the full RS-485 differential output swing, which is the common gotcha with 3.3 V transceivers — some don't meet the 1.5 V minimum differential output at the far end of a loaded bus. This one does. ## Lifecycle — no last-time-buy scramble No EOL notice, no last-time-buy clock ticking.","metaTitle":"SN65HVD1780D RS-485/RS-422 Transceiver, 115 kbps, 8-SOIC","metaDescription":"TI SN65HVD1780D half-duplex RS-485/RS-422 transceiver in 8-SOIC. 3.15 V to 5.5 V supply, -40°C to 125°C range, 50 mV hysteresis.","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":"115Kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 5.5V","Base Product Number":"65HVD1780","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/841cd41992f84285f75bf28fceb4b47c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1780D/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD1780D a direct replacement for SN65HVD1782D?","answer":"SN65HVD1780D and SN65HVD1782D are both half-duplex RS-485 transceivers in the same 8-SOIC footprint, but the 1782D typically supports a higher data rate.
