| FFF Compatibility | The physical footprint, 16-pin SOIC package dimensions, and pinout assignments are identical to the original device.The physical package is a narrow SOIC-16 (150 mil width) with matching lead spacing and dimensions.Operates on the same 4.5V to 5.5V supply voltage and fulfills the exact same quad differential driver role with improved power and temperature ratings. | The 16-pin SOIC package (D-suffix) has identical pinout assignments and dimensions.Uses the industry-standard narrow SOIC-16 package format (3.9mm width).Provides functionally identical quad RS-422 differential line driving on a 5V supply rail. | ||
 AI Summary | DS26LS31CM/NOPB by Texas Instruments: 4/0 Driver RS422, RS485 16-SOIC. | This is the direct CMOS modern equivalent of the obsolete bipolar DS26LS31CM. It is a pin-for-pin drop-in replacement that operates on the same 5V supply but offers vastly reduced power consumption and an extended operating temperature range. It is an active product and represents the lowest-risk replacement option.
| The AM26C31IDR is Texas Instruments' standard CMOS quad line driver and is actively manufactured. It serves as an excellent pin-compatible alternative, offering high noise immunity and reduced power consumption in the exact same SOIC-16 footprint.

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 DS26LS31CM/NOPB 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 DS26LS31CM/NOPB are the DS26C31TM/NOPB (Texas Instruments) and the AM26C31IDR (Texas Instruments), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Yes. The leading alternatives to the DS26LS31CM/NOPB are fit-, form- and function-compatible — the same package and pinout with matching key electrical specifications — so they drop in without PCB changes. Always confirm the parameters critical to your design against the alternative's datasheet before committing.
