Part Number: ISO7221M

Team,

For https://www.skyworksinc.com/en/products/isolation/si84xx-digital-isolators/si8422bb-is
Our cross ref tool does list ISO7721 and ISO6721as Drop-in replacement:
https://www.ti.com/cross-reference-search/singlepart?searchTerm=SI8422BB-D-ISR

-Which one of the other ISO7x21 can be used as drop-in replacement too?
        ISO7821 vs ISO7721vs ISO7521 vs ISO7421 vs ISO7321 vs ISO7221 vs ISO7021 vs ISO6721
-For example can ISO7221/A/B/C/M be an option?

It could make sense to as well list older device in the cross ref as some of them are on TI.COM stock.

    Hi AnBer,

    Thank you for posting to E2E! ISO7721 and ISO6721 in the 8-pin "D" package are drop-in replacements for SI8422BB-D-ISR. Most of our 2-pin ISOxx21 devices can be used as replacements so long as our customer's isolation and other performance requirements are met.

    ISO6721, ISO7721, ISO7321, ISO7021, ISO7221, ISO7421 and most of their automotive equivalents can be recommended as replacement options in the order listed here. The only exception is ISO6721"R" in the 8-pin "D" package which features a different pin configuration than the others. ISO7821, ISO7521, and ISO7421E-Q1 are not available in a "D" package. 

    Thank you for your feedback regarding listing older components as cross references. I will share this with our marketing team.

    Please let us know if there is more information we can provide.


    Respectfully,
    Manuel Chavez
