| FFF Compatibility | Identical SOIC-14 footprint, 3.90mm width, and pinout configuration.Same SOIC-14 package dimensions and physical footprint.Identical electrical ratings, including a 24mA output current capability and -40°C to 85°C operating range. | Identical standard SOIC-14 package pinout configuration.Matches the physical SOIC-14 (SOT108-1) outline and dimensions.Meets or exceeds all electrical parameters, providing the same 24mA output drive with an expanded operating temperature. | ||
 AI Summary | 74LCX125MX by onsemi: Buffer, Non-Inverting 4 Element 1 Bit per Element 3-State Output 14-SOIC. | This is the direct modern replacement from onsemi using the same LCX technology family and SOIC-14 package. It offers identical electrical parameters, 5V input tolerance, and a matching pinout, making it a true drop-in alternative.
| This is a highly reliable alternative from Nexperia using the widely adopted 74LVC technology family. It is fully pin-compatible and functionally identical, with the added benefit of a wider operating voltage range down to 1.2V and an extended temperature rating.

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 74LCX125MX 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 74LCX125MX are the MC74LCX125DR2G (onsemi) and the 74LVC125AD,118 (Nexperia USA Inc.), out of 4 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 74LCX125MX 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 74LCX125MX (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
