Product details

What this part is — and where it fits

The Analog Devices MAX22503EASD+ is a full-duplex RS-422/RS-485 transceiver in a 14-SOIC package. It handles one driver and one receiver at 100 Mbps.

Temperature grade and deployment context

Rated for -40°C to 125°C ambient, this transceiver belongs in equipment that lives outside a climate-controlled cabinet — motor drives on the plant floor, outdoor telecom gear, engine-adjacent electronics, or solar-string monitors. The full industrial temperature range also covers the cabin and chassis domains in automotive auxiliary systems, though the part carries no AEC-Q designation in the listing.

Frequently asked questions

Does MAX22503EASD+ support full-duplex RS422 at 100 Mbps with a 5V supply?

Yes. The part is a full-duplex transceiver rated for 100 Mbps, and its supply range covers 3V to 5.5V, so it runs on a 5V rail without issue.

Is MAX22503EASD+ compatible with a 3.3V supply?

Yes. The supply range is 3V to 5.5V, so 3.3V operation is within spec.
