For longer runs at lower rates the same part works fine; the driver slew is not limited, so the designer controls edge rate through termination and stub topology rather than a slow-mode pin. The 50 mV hysteresis on the receiver helps reject common-mode noise that couples onto the twisted pair in industrial environments.","metaTitle":"SN65HVD1793DR RS-485/RS-422 Transceiver, 10 Mbps, 14-SOIC","metaDescription":"TI SN65HVD1793DR full-duplex RS-485/RS-422 transceiver, 10 Mbps data rate, 5V supply, -40°C to 105°C, 14-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":"Tape & Reel (TR)","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":"$2.8845","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b38d061c4360ce75c40342dad0f5f015.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1793DR/alternatives.json"},"ai":{"faq":[{"question":"Can SN65HVD1793DR operate at 3.3V?","answer":"No. It is a 5 V-only transceiver and does not support 3.3 V logic levels on the bus or the digital interface."},{"question":"What is the closest pin-compatible alternative to SN65HVD1793DR?","answer":"Within the same base family, the SN65HVD1792 is a half-duplex variant. The SN65HVD1793DR is full-duplex, so the two are not pin-compatible substitutes.
