It handles point-to-point RS-422 links and multi-drop RS-485 buses, pushing data at up to 2Mbps over twisted-pair cabling. The supply range of 3V to 3.6V ties it to 3.3V logic systems — common in telecom line cards, industrial control backplanes, and building-automation gateways that need a differential driver bank without pulling a separate 5V rail. ## 2Mbps data rate — what it buys you on the bus The 2Mbps data rate is the driver's switching ceiling. At this speed on an RS-485 bus, cable length is limited to roughly 400 metres before signal degradation from DC resistance and capacitance becomes a problem. For shorter runs — inside a cabinet or across a factory floor — 2Mbps clears most Modbus RTU, Profibus, and generic UART links comfortably. If your application needs 10Mbps or higher, this part is not the fit; look at the MAX3040 series instead. The 16-SOIC narrow-body (3.90 mm width) is a standard, well-understood footprint. No exotic land pattern, no hidden thermal pad — just a straightforward SOIC that reflows cleanly with a typical lead-free profile. The Tube shipping medium is fine for prototype and low-volume builds; if your pick-and-place line runs tape-and-reel only, confirm the reel option exists on the order line. No last-time-buy window has been announced. For procurement planning, there is no imminent supply-risk trigger on this order code.","metaTitle":"MAX3031ECSE+ RS422/RS485 Driver, 2Mbps, 16-SOIC","metaDescription":"MAX3031ECSE+ is a 4/0 RS422/RS485 line driver from Analog Devices.
