The 10 Mbps data rate is the upper end for RS-485; if your application only needs 115.2 kbps or 1 Mbps, this part still works, but you are paying for speed margin you may not use. For sub-1 Mbps links, a slower-slew-rate variant (like the SN65HVD1792) could reduce radiated emissions. ## Package and footprint — 14-SOIC If you already have a layout for a 14-pin SOIC RS-485 part, the SN65HVD1793D drops in without a board spin. The tube shipping medium is fine for prototype and low-volume builds; for reflow assembly, request the tape-and-reel variant (SN65HVD1793DR) to feed the pick-and-place.","metaTitle":"SN65HVD1793D RS-422/RS-485 Transceiver, Full Duplex, 10 Mbps","metaDescription":"Texas Instruments SN65HVD1793D full-duplex RS-422/RS-485 transceiver in 14-SOIC. 10 Mbps data rate, 50 mV hysteresis, -40°C to 105°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":"10Mbps","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"65HVD1793","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~105°C","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/57749660dbaef6e6826c1fb9bcc7d37f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1793D/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD1793D obsolete?","answer":"No. The manufacturer lists the product status as Active.
