AI Summary

DM74ALS240AWM by onsemi: Buffer, Inverting 2 Element 4 Bit per Element 3-State Output 20-SOIC.

The SN74ALS240ADW is a direct drop-in replacement from the exact same logic family (74ALS). It provides 100% electrical, physical, and timing compatibility with the obsolete DM74ALS240AWM. This is the safest and highest-confidence replacement option.

  • Direct drop-in replacement from the same 74ALS logic family
  • Matches original electrical characteristics (15mA/24mA drive) and timing exactly
  • Active lifecycle status from Texas Instruments

The MC74ACT240DWR2G is an active advanced CMOS alternative from the original manufacturer (onsemi). It features TTL-compatible inputs and significantly lower power consumption while offering a wider operating temperature range and higher current drive capability.

  • Modern advanced CMOS logic family (74ACT) with active lifecycle support
  • Exceeds original output drive capability (24mA High and Low)
  • Significantly lower standby power consumption and faster propagation delay
  • Faster CMOS transition edge rates can occasionally introduce signal ringing on long, poorly terminated PCB traces.

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 DM74ALS240AWM 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.
