    Hi Mitchell,

    The markings on the die are for internal lot tracking and environmental category, as indicated by (4) shown above in the datasheet screenshot. I was able to look up the devices above, and they are genuine TI devices that were manufactured in October of 2023.

    Please let me know if there are further questions.

    Best regards,
    Carrie
