That is the ceiling for this transceiver — it is not a high-speed RS-485 part like the 10 Mbps or 50 Mbps variants in the same family. If your bus runs at 115.2 kbaud or slower, this part fits."},{"question":"What is the difference between SN65HVD1791D and SN65HVD1790D?","answer":"The SN65HVD1791D is a full-duplex transceiver (one driver, one receiver), while the SN65HVD1790D is half-duplex (one driver and one receiver sharing the bus pins, requiring direction control). Both run at 115 kbps on a 5 V supply in the same SOIC-14 footprint. The choice comes down to whether your bus needs simultaneous transmit and receive (full duplex) or a shared two-wire bus (half duplex)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD1791D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD1791D when reusing this data.
