SN65C1168E-SEP: Displacement Damage

Andres Ramones

Part Number: SN65C1168E-SEP
Other Parts Discussed in Thread: TPS7H2221-SEP, THVD9491-SEP

Hi.

Can you guys confirm that TI didn't consider the part (SN65C1168E-SEP) to be sensitive to DDD based on the fabrication technology used?

Hi Andres,

I can check with our high-rel team but can you clarify what DDD stands for?

Thanks for clarifying Andres.

I got feedback from the team responsible for this device:

"Not necessarily because of the technology. The technology is LBC3s, which has bipolar technology and is not pure CMOS.

We don’t have any NDD data on this device or process to suggest it is susceptible or not."

If I need to replace the part, do you have any part that has >30krad and NDD data?

BOBBY If I replace the part with THVD9491-SEP, can I use NDD data from TPS7H2221-SEP? Both use LBC9 technology

Hi Andres,

Thanks for your patience here. Bobby is out of office. We are following up internally to see if this is possible. But I will say based on my current knowledge, the answer is likely no. These devices have very different transistor counts so it will not be an apples to apples comparison.

Our other space grade transceivers do not have NDD reports like that one you showed. But they do have the TID reports: https://www.ti.com/product-category/interface/rs-485-rs-422-transceivers/products.html#1498=Space&

Best,

Ethan

Hi Andres,

I reached out to our space power team, and they confirmed the report shouldn't be transferred for the reason I mentioned above. These are very different devices even though they share the same process.

Best,

Ethan
