| FFF Compatibility | Standard 20-pin SOIC pinout matches the target part exactly with no layout changes required.Standard 20-SOIC (0.295 inch, 7.50mm body width) package is physically interchangeable.Identical bipolar 74ALS logic family with identical 4.5V to 5.5V supply and 0°C to 70°C operating temperature. | The SOIC-20 pinout matches the standard 74xx240 inverting octal buffer configuration exactly.Housed in a standard 20-SOIC package with an identical physical footprint.Operates on the same 5V supply and features TTL-compatible inputs, making it fully compatible with existing 5V TTL systems. | ||
 AI Summary | DM74ALS240AWM by onsemi: Buffer, Inverting 2 Element 4 Bit per Element 3-State Output 20-SOIC. | The SN74ALS240ADW is a direct drop-in replacement from the exact same logic family (74ALS). It provides 100% electrical, physical, and timing compatibility with the obsolete DM74ALS240AWM. This is the safest and highest-confidence replacement option.
| The MC74ACT240DWR2G is an active advanced CMOS alternative from the original manufacturer (onsemi). It features TTL-compatible inputs and significantly lower power consumption while offering a wider operating temperature range and higher current drive capability.

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 onsemi DM74ALS240AWM 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 onsemi DM74ALS240AWM are the SN74ALS240ADW (Texas Instruments) and the MC74ACT240DWR2G (onsemi), 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 DM74ALS240AWM 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 DM74ALS240AWM (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
