The receiver inputs are RS-485 compliant across the full common-mode range, and the 30 mV hysteresis helps reject noise on differential pairs that share a cable tray with drives or solenoids. That means no last-time-buy pressure for current production runs, and it remains a valid selection for new designs.","metaTitle":"TI THVD1450DGKR RS-485 Transceiver, 50 Mbps, Half-Duplex","metaDescription":"Texas Instruments THVD1450DGKR RS-485 transceiver, half-duplex, 50 Mbps data rate, 3V to 5.5V supply, -40°C to 125°C, 8-VSSOP.

The logic inputs and outputs are referenced to the supply, so a 3.3V supply gives 3.3V logic levels."},{"question":"What is the closest pin-compatible alternative to THVD1450DGKR?","answer":"Within the same base product family, the THVD1450 series includes several speed and duplex variants. The THVD1450DGKR is the half-duplex 50 Mbps option in the 8-VSSOP package. For a full-duplex or different speed grade, check the THVD145x family datasheet for pin-compatible siblings — the base product number THVD1450 shares the same footprint across the series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/THVD1450DGKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/THVD1450DGKR when reusing this data.
