Original question:

CD74HC10: Radiation specification

LM139: LM139D - Radiation Specification

Paul Weiss
Prodigy 30 points

Part Number: LM139

Tool/software:

I am looking for radiation testing data.  We need to verify if it meets our requirements for LEO.  Looking for TID and ELDRS data. This is a 5-year mission life.

Thank you

    Hello Paul,

    We cannot speculate on a device that has not been radiation tested.

    The LM139DR is a native TI commercial device. That die process is not tested for radiation.

    The majority of our "QML" and rad-hard ("V") space devices are based on the ex-National Semiconductor process and design.

    The National LM139 die process and design is pretty much the same across the families, but the true rad-hard "QMLV" devices can have an extra processing step - so they are not /exactly/ the same as the QML or commercial devices (maybe ~98% similar)

    The LM139-N family is the commercial version based on the same basic National design.

    The LM139AQML family would be a bit closer - as the QMLV (rad hard) versions are the same die just rad tested..

    Lot test results are available for the /883, B, QML and QMLV device from the QCI system:

     https://qci.itg.ti.com/

    Please also see the  "Technical Documentation" section of the LM139AQML page for the radiation reports:

     https://www.ti.com/product/LM139AQML#tech-docs

    And the Radiation Handbook:

     https://www.ti.com/seclit/eb/sgzy002a/sgzy002a.pdf

    Of course, this is just for guidance and TI does NOT guarantee radiation performance for any non-rad hard device. Any space use, at any level, would be at your own risk.
