TLK2711-SP: max allowed radiation exposure

Part Number: TLK2711-SP

Hi Team, 

what is the max. allowed radiation exposure. I found the value 25krad in our documents but not in the radiation test report. There I could only find this figure: 

What does ICCQ mean here?

I'm wondering what the green paragraph means. For me it implies that the device was test up to 100krad and there were no issues?

Thanks

    As per the report this device was tested with level up to 100krad and no issues were observed. ICCQ is a device supply current. Typically, when device degrades you first see variation in the current.

    Thanks,

    Hi Rodrigo, 

    thanks for the response. In the graph in the initial thread, ICCQ is out of limits from 25krad. I assume that means that the device can only withstand 25kRad. Correct me if I'm wrong with my assumption?

    Regards

    Hi,

    See below text from the report.

    "The bias board voltages and currents were monitored at the start and end of each exposure period. All test equipment is property of ICS with the exception of the Shepherd Gammabeam 150-C and the DUTs. The exposure groups by serial # and exposure level are as follows: 25krads (Si) TID —S.N. 46, 69, & 89. 50krads(Si) TID —S.N. 108-110. 75krads(Si) TID —S.N. 113-115. 100krads(Si) TID —S.N. 121-123. Controls —S.N. 106, 116, 124, & 125. No unusual events were observed during the radiation exposure of the TLK2711, 1.6-2.7 GBPS Transceivers."

    Thanks,
