For pure 5 V systems the interface is direct. ## 10 Mbps — cable length and signal integrity budget At 10 Mbps the rise time is fast enough that stub length and termination matter. For a 10 Mbps link, keep the stub from the transceiver to the bus connector under 30 cm and place a 120 Ω termination resistor at each end of the cable. The 30 mV receiver hysteresis gives about 600 mV of noise margin on a 5 V differential bus, which handles typical ground shifts in industrial environments. If your cable run exceeds 100 m at this data rate, expect to drop to a lower baud rate — the RS-485 standard trades speed for distance.

For tape-and-reel, order the SN65HVD485EDGKR — same die, same 8-VSSOP footprint, same electrical specs, just different packaging format."},{"question":"Is SN65HVD485EDGKG4 RoHS compliant?","answer":"The DGK4 suffix indicates a green/RoHS-compliant finish per TI's standard lead-free plating. The part is free of restricted substances under the current EU RoHS directive."},{"question":"Can SN65HVD485EDGKG4 be used as a replacement for SN65HVD485ED?","answer":"Yes — the SN65HVD485EDGKG4 is the 8-VSSOP package variant of the base SN65HVD485ED design. The only difference is the package: the -ED suffix typically ships in an 8-SOIC, while the -EDGKG4 is the smaller 8-VSSOP. Verify the footprint matches your PCB layout before substituting."},{"question":"How many drivers and receivers does SN65HVD485EDGKG4 have?","answer":"One driver and one receiver (1/1). This is a single-channel half-duplex transceiver."},{"question":"Is SN65HVD485EDGKG4 compatible with 3.3V logic?","answer":"The receiver output (RO) swings from GND to VCC, so a 3.3 V MCU input may see a 5 V logic-high — check the MCU's 5 V tolerance. The driver inputs (DI, DE, RE) have TTL-compatible thresholds (VIH ~2.0 V), so a 3.3 V logic-high is sufficient to drive them. A level shifter on RO is recommended for 3.3 V-only controllers."},{"question":"What is the difference between SN65HVD485EDGKG4 and SN65HVD485EDGKR?","answer":"The -DGKG4 suffix indicates Tube packaging; the -DGKR suffix indicates tape-and-reel packaging. The die, electrical specs, and 8-VSSOP package are identical. Choose the format that matches your pick-and-place feeder or volume requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD485EDGKG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD485EDGKG4 when reusing this data.
