AI Summary

DM74LS132N by onsemi: NAND Gate IC 4 Channel Schmitt Trigger 14-MDIP.

This is the direct manufacturer-recommended replacement for the obsolete DM74LS132N. It belongs to the same 74LS series and provides identical electrical and physical characteristics with no board modifications.

  • True bipolar LS-TTL drop-in replacement with identical electrical characteristics
  • Directly pin-to-pin compatible in standard DIP-14 package
  • No pull-up resistors or level shifting required when interfacing with other TTL logic

This is a high-speed CMOS alternative designed specifically with TTL-compatible inputs. It serves as an excellent upgrade that drops directly into the socket while reducing quiescent current draw.

  • Significantly lower quiescent power consumption (CMOS technology) compared to the original LS-TTL gate
  • TTL-compatible input voltage thresholds, enabling direct interfacing with other 74LS TTL circuits
  • Pin-compatible drop-in replacement in the same DIP-14 style footprint
  • CMOS output drive characteristics differ slightly from bipolar LS-TTL under heavy capacitive loads.

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 DM74LS132N 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.
