    Hello  , 

    I appreciate your patience - this is a device that comes from TI's acquisition of National Semiconductors many years ago, so we had to dig into the nomenclature. In this case we believe the 17 in ZM17AB should refer to "last digit of the year" and "week of the year" respectively, so this is either 2011 or 2021, week 7 (February).

    If you have access to the shipping label, which is usually attached the the shipping box and the reel, it would also be something you can find there.

    Let us know if there is anything else we can clarify.

    Best Regards,
    Victor Salomon
