Silicon Labs Digital Isolation, lifetime

Hi

For a new design, I am considering the Silicon Labs Digital Isolation IF IC Si8421:

They state long lifetime, 60 years at 400VRMS.

Anyone have practical experience with this IC series, specifically regarding lifetime/endurance? Using them for level shifting with fast transients?

Also, general experience with Silicon Labs as a company?

Thanks

Klaus

It's NRND.

We've seen these get into strange states where the output did not reflect the input. TI and ADI make nice isolators.

And NRND is?

Did you discover what the cause was for the malfunction?

Cheers

Not Recommended for New Design. Deprecated. Scheduled for obsolescence.

We have no way to do that. We just used something else.

ADI has an appnote about their iCoupler series, which talks about the DC stability of their design. Seems that cheaper brands only transmit the edges (hence the input and output can get out of sync); Analog's send keep-alive blips corresponding to state. They also have a timeout state (if the transmitter stops blipping).
