| FFF Compatibility | The SOIC-16 footprint and complete 16-pin assignment are identical to the original bipolar AM26LS31CD.Housed in the identical SOIC-16 narrow package with a body width of 3.90mm (0.154 inches).Performs the same quadruple differential line driver function, meeting RS-422 standards while consuming less power. | Features the exact same 16-pin RS-422 driver configuration and enable pin logic (G and /G).Packaged in the same SOIC-16 (0.154 inch width) package matching the footprint.Meets or exceeds all RS-422 transmission electrical specifications. | ||
 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.
| 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.

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 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.
The closest qualified second sources for the Texas Instruments AM26LS31CD are the AM26C31IDR (Texas Instruments) and the DS26C31TM/NOPB (Texas Instruments), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
