ISO7221C: ISO7221A vs ISO7721D

Part Number: ISO7221C
Other Parts Discussed in Thread: ISO7721,

Good morning, everyone.
In my application I have to isolate a canbus line that works at 500kbps.
Which of the two isolators do you think is the most suitable?

Comparing the two isolators from the DATASHEET I see that the ISO7721 model has more performance than the ISO7221c but the price of the ISO7721 is lower than the ISO7221.

    Good Morning Robert, 

    The ISO77xx series of digital isolators are our latest family and have better performance than ISO72xx. We have also cost optimized the parts on our side, so we are able to offer our newest isolators at a cost competitive price compared to our previous generations. So, in this case, you do not have to trade off performance for cost. ISO77xx gives you both. 

    I would recommend ISO7721 as it has better performance. 

    Please let me know if you have any additional questions. 

    Best regards, 

    Dan
