Radiation data | LM139-SP

Other Parts Discussed in Thread: LM139-SP, LM139

Dear Sir/Madam,

I would like to find out the radiation data for LM139-SP covers only TID40kRad/sec.

Any reason why the Single Event Latch-up data was not reflected on the datasheet?

Hope you could clear my doubts.

Thanks

Regards,

Nick

    Hello Nick,

    TI offers two space grade versions of the LM139:
    LM139-SP and LM139QML-SP.

    The LM139QML-SP comes from TI's acquisition of National Semiconductor. It is rated to 100 krad and is ELDRS-free. It has decades of space flight heritage.

    The LM139 is a classic bipolar product. Single event latch-up was discovered to be an issue with CMOS products and bipolar products traditionally do not list SEE test results.

    There is an SEE paper for the LM139QML-SP on the TI website. An easy link is:
    ti.com/radiation

    See this link for general SEL testing on a wide variety of bipolar products:
