8-SOIC RS-485 transceiver for industrial bus nodes
The MAX1483CSA+T: It operates at a data rate of 250 kbps over a single twisted pair, making it a fit for Modbus, Profibus, and other differential serial bus applications in factory-floor and building-automation controllers.
Supply rail, receiver hysteresis, and temperature grade
The 75 mV receiver hysteresis filters noise on the differential bus — without it, a floating or lightly-driven line can oscillate between logic states, corrupting the frame. For extended-temperature or outdoor bus drops, a -40 °C to +85 °C grade (e.g., MAX1483ESA+) would be the correct selection.
Active production and compliance standing
ROHS3 compliant — no exemptions for lead in solder or any of the six restricted substances above threshold. The part ships in tape-and-reel (TR) or cut-tape (CT) options, accommodating both high-volume reel feeds and prototype quantities.
