AI Summary

AM26LS31CD by Texas Instruments: 4/0 Driver RS422, RS485 16-SOIC.

The AM26C31IDR is the official, active CMOS successor to the obsolete bipolar AM26LS31CD. It offers identical pinout compatibility and physical dimensions while providing a wider temperature range and significantly lower power consumption. It is highly recommended as a direct drop-in replacement for modern designs.

  • Direct pin-for-pin compatible replacement
  • Extended industrial temperature range of -40°C to 85°C vs commercial 0°C to 70°C
  • Modern CMOS technology with dramatically lower static power consumption (ICC of 2-3 mA max vs up to 80 mA)
  • Slightly different output rise/fall propagation times due to CMOS vs. Bipolar transition, though fully compatible in RS-422 networks.

The DS26C31TM/NOPB is a highly reliable CMOS quad differential line driver from Texas Instruments. It functions as a direct pin-compatible alternative to the AM26LS31CD, offering lower static power consumption and a wider industrial operating temperature range. This is an excellent alternative from an adjacent product family.

  • Pin-for-pin compatible drop-in replacement
  • Active lifecycle status in long-term production
  • Extended temperature range of -40°C to 85°C
  • CMOS output characteristics may slightly differ from the original bipolar line driver under heavy load.

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 Texas Instruments AM26LS31CD 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.
