Hi Fausto,

Thanks for reaching out.

No, The ISO674x (eg ISO6741) is not radiation hardened. I am assuming you are asking in regards to aerospace applications, in which case the ISO141-SEP device is a great option. The ISOS141-SEP device is our Radiation tolerant digital isolator that supports up to 100Mbps and comes in the DW package. This device has 4 channels total (3 forward and 1 reverse channels) and is commonly used for space applications. Please see more information about this device here: https://www.ti.com/product/ISOS141-SEP

Hi Fausto,

Thanks for your reply.

Since these isolators are radiation tolerant, they do tend to be priced higher. I will check with my team on your request.
