The 70 mV of receiver hysteresis gives you noise margin on long cable runs without external biasing resistors. The full industrial temperature span means you don't derate for ambient heat soak or cold-start conditions. Surface-mount 8-SOIC footprint keeps the board area small and matches standard RS-485 transceiver layouts.","metaTitle":"SN65HVD74D RS-485/RS-422 Transceiver, 20 Mbps, 8-SOIC","metaDescription":"TI SN65HVD74D full-duplex RS-485/RS-422 transceiver. 20 Mbps data rate, 3V-3.6V supply, -40°C to 125°C.

No level shifting needed if the rest of the logic runs at 3.3V."},{"question":"Is SN65HVD74D compatible with 5V logic?","answer":"The supply is 3V to 3.6V, so the transceiver itself runs on 3.3V. Driving the DI pin from a 5V logic output exceeds the absolute maximum ratings — use a level translator or a resistive divider if the controller side is 5V."},{"question":"What is the equivalent or replacement for SN65HVD74D?","answer":"The SN65HVD74D is a full-duplex RS-485 transceiver in an 8-SOIC package running at 20 Mbps on a 3.3V supply. Pin-compatible alternatives within the same TI family include the SN65HVD72D (half-duplex, lower data rate) and the SN65HVD75D (half-duplex, 20 Mbps). For a full-duplex drop-in, the SN65HVD74 is the direct match — verify the suffix for package and temperature grade."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD74D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD74D when reusing this data.
