    8 bits and only 0 to 7? Sure that's not 0 - 255? What is your meaning of "HexDisplay"?

    Try a 7 segment driver like a 7447.

    "Help me" as the subject is unnecessary and not helpful; you should have stated at least part of the problem in the subject line.

    You should post homework questions in the Homework Help forum.

    Since this is obviously homework, we can't do it for you.

    However, you might look at 4000-series CMOS IC's and 74xx series TTL IC's, and find the 7-segment LED drivers. Decide which, if any, might work for your assignment.
