| FFF Compatibility | Uses the identical SC-88A (SC-70-5) footprint with the exact same pin configuration (1-OE, 2-A, 3-GND, 4-Y, 5-VCC).Identical package dimensions and physical footprint from the same manufacturer.Exact functional equivalent operating at the same 2V to 5.5V supply and retaining the same speed and drive strength. | Fully pin-compatible in the SOT-353/SC-70-5 package footprint.Matches the physical SOT-353 (SC-88A) package style and dimensions.Operating temperature range is slightly narrower (-40°C to 125°C vs -55°C to 125°C). | ||
 AI Summary | NLVVHC1G126DFT1G by onsemi: Buffer, Non-Inverting 1 Element 1 Bit per Element 3-State Output SC-88A (SC-70-5/SOT-353). | This is onsemi's modern direct replacement for the obsolete NLV-prefixed part number. It transitions the part to the new suffix-based automotive nomenclature while keeping the exact same physical silicon, package, and specifications.
| Nexperia's automotive-grade LVC single buffer is an excellent second-source option. It offers wider supply range and stronger drive strength, though its low-end temperature limit is slightly narrower.

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
The onsemi NLVVHC1G126DFT1G is in its last-time-buy phase — the manufacturer has announced end-of-life and is taking final orders only. If you need ongoing supply, the alternatives on this page are active replacements.
The closest qualified second sources for the onsemi NLVVHC1G126DFT1G are the MC74VHC1G126DFT1G-Q (onsemi) and the 74LVC1G126GW-Q100H (Nexperia), out of 6 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 NLVVHC1G126DFT1G 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 NLVVHC1G126DFT1G (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
