| FFF Compatibility | Mounts on the same SOIC-14 footprint. However, pins 9/10 (Input 3A/3B) and pins 12/13 (Input 4A/4B) are swapped compared to DM74AS1000AM. Since these are inputs to symmetric 2-input NAND gates, they are logically interchangeable.Housed in an identical 14-SOIC (0.154 in, 3.90mm width) standard package.Operates over the identical 4.5V to 5.5V supply range and meets or exceeds all performance specifications. | Mounts on the same SOIC-14 footprint.

 AI Summary | DM74AS1000AM by onsemi: NAND Gate IC 4 Channel 14-SOIC. | The SN74AS1000ADR is the most direct active replacement, offering identical electrical driver performance and delay specifications. While the physical pin layout has a logical swap of the symmetric NAND gate inputs, it operates identically in all standard circuit configurations.
| The SN74ALS1000ADR serves as a lower-power, slower-speed alternative from the ALS logic family. It is highly suitable if the design does not strictly require the high-speed 4ns propagation delay or the full 48mA output drive capability of the original AS family.

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 DM74AS1000AM 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 DM74AS1000AM are the SN74AS1000ADR (Texas Instruments) and the SN74ALS1000ADR (Texas Instruments), out of 3 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 DM74AS1000AM 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 DM74AS1000AM (onsemi) is a part in the Logic category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
