    Hello Jack,

    Unfortunately, because of product counterfeiting activities TI is unable to provide lot and date code device marking information for their products. Such information is used by counterfeiters to make counterfeit product appear legitimate. If you have the shipping tubes or product reels they should provide you with the lot and date information.

    If you obtained the product directly from TI, or from an authorized TI distributor, the product should be genuine TI product. 

    Regards, Thomas
