This eliminates a level-shifter IC and its associated propagation delay, which matters for timing closure on half-duplex turnarounds at higher baud rates. ## Industrial temperature and package — field-proven footprint The 8-SOIC (3.90 mm width) footprint is a standard layout shared across the 65HVD08 family, so a board designed for the DR variant reuses the same copper pattern.","metaTitle":"SN65HVD08DG4 RS422/RS485 Transceiver, Half-Duplex, 3V-5.5V","metaDescription":"Texas Instruments SN65HVD08DG4 half-duplex RS422/RS485 transceiver in 8-SOIC.

The supply voltage range of 3V to 5.5V covers both 3.3V and 5V rails, so the transceiver interfaces directly with either logic family without a level translator."},{"question":"What is the difference between SN65HVD08DG4 and SN65HVD08DR?","answer":"Both are the same half-duplex RS422/RS485 transceiver in an 8-SOIC package. The DG4 suffix indicates tube packaging, while the DR suffix indicates tape-and-reel. Electrical specifications and footprint are identical."},{"question":"Can SN65HVD08DG4 be used for RS422?","answer":"Yes. The transceiver explicitly supports the RS422 protocol. Note that it is half-duplex, so it handles one direction at a time on a single twisted pair — not full-duplex four-wire RS422."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD08DG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD08DG4 when reusing this data.
