AI Summary

74LCX14MX_NL by onsemi: Inverters FINISHED GOOD.

This is the direct, active replacement from onsemi (which acquired Fairchild). It matches the electrical characteristics, 5V input tolerance, and physical SOIC-14 dimensions of the obsolete original part.

  • Direct active replacement from onsemi (merging the Fairchild/onsemi logic portfolios)
  • Identical electrical specs and timing parameters (6.5ns max propagation delay)
  • True pin-for-pin drop-in replacement with identical package dimensions

This is an active, highly robust alternative from Texas Instruments using the 74LVC logic family. It matches the +/-24mA drive and 5V input tolerance while offering a wider temperature and supply voltage operating window.

  • Wider operating temperature range (-40°C to 125°C vs -40°C to 85°C)
  • Broader operating supply voltage range (1.65V to 3.6V vs 2.0V to 3.6V)
  • Slightly faster propagation delay (6.2ns max vs 6.5ns max)

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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 74LCX14MX_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.
