    Hello Kum,

    For small packages, where there is not a lot of room, both alphanumeric and binary "dash" codes are used.

    "T1IS" which is one of the designations for the TL331IDBV.

    The dashes above and below the text are a BCD binary code denoting the data and lot codes. The top row is the last digit of the year, and the bottom row is the month.

    Both have a top code of "1000", or "8", or year 2018

    The left has a code of "0001" (1, or January) and the right is "1010" (10, or October).

    So the left is January 2018, and the right is October of 2018.
