    How would you enable the count and disable the load on a 74190 chip?

    Please make thread titles more meaningful. "Homework help" is a bit vague and rather redundant considering that this is the Homework Help section of the forum.
    I have edited the thread title for you.

    Thanks, I've tried that, but I am unclear on how to enable the count

    When the part is counting:
    Load is high, CTEN is low.
