| FFF Compatibility | Matches the target's 8-SOIC pinout and PCB land pattern exactly with no board changes required.Housed in the exact same 8-SOIC narrow package (3.90mm width).Identical functional parameters, operating voltage (3.0V to 3.6V), and industrial temperature range (-40°C to +85°C). | Standard 8-SOIC RS-485 pinout matches the target board layout directly.Standard 8-SOIC package dimensions match the target package footprint.Meets all target safety parameters and provides a slightly higher data rate of 12Mbps under the same 3.3V operating voltage. | ||
 AI Summary | ADM3485EAR by Analog Devices: 1/1 Transceiver Half RS422, RS485 8-SOIC. | This is the direct RoHS-compliant (lead-free) replacement from the original manufacturer. It is an active, long-lived part that operates with identical parameters and acts as a seamless drop-in transition for obsolete leaded designs.
| An active, high-reliability transceiver that represents a direct cross-functional replacement from the Maxim brand of Analog Devices. It matches the original's physical footprint while offering enhanced ESD protections and a slightly faster maximum data rate.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Analog Devices ADM3485EAR is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Analog Devices ADM3485EAR are the ADM3485EARZ (Analog Devices Inc.) and the MAX3485EESA+ (Analog Devices Inc./Maxim Integrated), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the ADM3485EAR are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The ADM3485EAR (Analog Devices) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
