| FFF Compatibility | Identical package (16-SOIC, 0.154" width) and pin assignments since it is from the same product series.Identical physical form factor, lead pitch, and package drawing.Exact same electrical performance, logic family, and absolute maximum ratings. | Matches the standard 74HC123 SOIC-16 footprint and pinout assignment exactly.Standard SOT109-1 (16-SO) package matching the physical dimensions of the original TI part.Operating temperature range is slightly narrower (-40°C to 125°C) than the original TI part (-55°C to 125°C). | ||
 AI Summary | CD74HC123M by Texas Instruments: Monostable Multivibrator 25 ns 16-SOIC. | This is the exact same chip from Texas Instruments, but supplied in Tape & Reel packaging (96 suffix) instead of the obsolete tube package. It is an active, direct drop-in replacement with no physical or electrical differences.
| An active second-source option from Nexperia in the same 16-pin SOIC package. It has an identical pinout and layout, though the minimum operating temperature is rated down to -40°C instead of -55°C.

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 Texas Instruments CD74HC123M 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 Texas Instruments CD74HC123M are the CD74HC123M96 (Texas Instruments) and the 74HC123D,653 (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 CD74HC123M 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 CD74HC123M (Texas Instruments) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
