No footprint change is needed when substituting between common 8-pin SOIC parts from the same class. The surface-mount package is suitable for reflow soldering per JEDEC J-STD-020; the tube packing means the parts ship in anti-static tubes rather than tape-and-reel, so pick-and-place feeders may need a tube feeder or manual loading for high-volume lines. ## Active production and compliance status The device is ROHS3 Compliant, meeting the latest EU RoHS exemption-free requirements for lead-free assembly.","metaTitle":"MAX490ESA+ RS-485/RS-422 Transceiver, Full Duplex, 2.5Mbps","metaDescription":"MAX490ESA+ Analog Devices RS-485/RS-422 transceiver, full duplex, 2.5Mbps data rate, 70mV hysteresis, -40°C to +85°C, 8-SOIC.
