It provides four independent drivers in a single 16-SOIC wide-body package, with no integrated receivers — a pure driver-only part for transmit-side applications where the receive path is handled separately. The 250 kbps data rate suits moderate-speed industrial serial links, including PLC-to-drive interfaces, building automation buses, and instrumentation networks where cable lengths reach several hundred metres at this baud rate. ## Supply and temperature — fit for industrial panels The supply range is 4.75 V to 5.25 V. Operating temperature spans -40°C to 85°C. ## Package and handling — tube, not tape For automated pick-and-place lines, plan for tube-fed feeders or a transfer to tape at the contract manufacturer. The 16-SOIC wide-body footprint (7.50 mm body width) is standard and matches the supplier device package code 16-SOIC. ## Lifecycle and compliance — no obsolescence risk It is ROHS3 compliant, covering the latest EU restriction on hazardous substances without exemptions. No lead-free finish concerns for global shipping or RoHS-regulated markets.","metaTitle":"MAX3040EWE+ RS-422/RS-485 Driver IC, 250 kbps, 16-SOIC","metaDescription":"MAX3040EWE+ is a 4/0 RS-422/RS-485 driver IC with 250 kbps data rate, 4.75V–5.25V supply, -40°C to 85°C range, 16-SOIC package.
