 AI Summary | 74LCX14MTC by onsemi: Inverter IC 6 Channel Schmitt Trigger 14-TSSOP. | This part is the exact same component as the original but packaged in Tape & Reel (MTCX) instead of a Tube (MTC). Since the original part is obsolete, switching to the active Tape & Reel version allows direct drop-in sourcing without any design modifications.
| The MC74LCX14DTR2G is onsemi's modern active series replacement for the 74LCX14. It offers identical electrical parameters, package dimensions, and pin compatibility, serving as a reliable first-source drop-in replacement.

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 74LCX14MTC 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 74LCX14MTC are the 74LCX14MTCX (onsemi) and the MC74LCX14DTR2G (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 74LCX14MTC 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 74LCX14MTC (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
