Product details

SOIC-8 footprint and board integration

Housed in an 8-SOIC (0.154-inch body width, 3.90 mm width) surface-mount package, the MAX490ESA+ shares the standard SOIC-8 land pattern used by hundreds of RS-485 transceivers. 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.

Frequently asked questions

What is the data rate and protocol support of MAX490ESA+?

The MAX490ESA+ supports both RS-485 and RS-422 protocols at data rates up to 2.5 Mbps. It operates in full-duplex mode with one driver and one receiver, making it suitable for point-to-point or multi-drop bus configurations where simultaneous transmit and receive is required.

What compliance documentation does Analog Devices provide for MAX490ESA+?

Analog Devices provides RoHS3 compliance for the MAX490ESA+. The part is also covered by the standard Analog Devices material declaration and conflict minerals reporting available through their compliance portal. No UL or IEC certification is listed for this transceiver on the record.
