| FFF Compatibility | The part is the direct, lead-free active replacement belonging to the exact same series with identical pinout and nomenclature.Shares the identical 20-TSSOP package and body dimensions.Operates on the identical 2.0V to 3.6V supply range with equivalent 24mA drive capabilities and propagation delays. | Pins are physically and electrically compatible, but naming nomenclature in the datasheet differs slightly (inputs named A1-A8 vs I0-I7, outputs named Y1-Y8 vs O0-O7, and active-low enables labeled OE vs /OE).Housed in an identical 20-TSSOP package with matching physical dimensions.Offers identical 24mA drive strength and 3-state logic operations while expanding operating voltage down to 1.65V. | ||
 AI Summary | 74LCX541MTCX_NL by onsemi: Buffers & Line Drivers FINISHED GOOD. | This is the direct active drop-in replacement from the same manufacturer. The '_NL' suffix on the obsolete part merely denoted 'No Lead' (Pb-free) under old Fairchild nomenclature, whereas the active '74LCX541MTCX' is fully RoHS/Pb-free compliant by default. This alternative maintains complete parity across all electrical, physical, and nomenclature specifications.
| This is a highly reliable second-source alternative from Texas Instruments from the active 74LVC family. It features identical flow-through layout and output drive capability while offering a wider supply voltage range down to 1.65V and an extended operating temperature ceiling. Slight variations in pin name nomenclature exist in the documentation but do not affect board design or physical mounting.

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 74LCX541MTCX_NL 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 74LCX541MTCX_NL are the 74LCX541MTCX (onsemi) and the SN74LVC541APWR (Texas Instruments), 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 74LCX541MTCX_NL 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 74LCX541MTCX_NL (onsemi) is a part in the Buffers & Line Drivers category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
