UC1846-SP: Differences between the radiation hardened and commercial dies

HI,

There was a previous question regarding the fabrication processes for the standard devices

" Are the UC1846-SP and UC1856-SP fabricated using any special process for radiation hardening such as SOI. Aside from the obvious packaging differences, is the Die the same as the standard versions UC2846, UC3846 etc? i.e. same Mask, same fabrication process. If not the same, then please could you explain the differences."

I can see Daniel's response that a solid answer will be available soon enough. 

Request you to clear this query

Thanks
Nandha
