    I am using a 74ls373 to drive six analog switches. My configuration is
    pretty simple; 6 momentary switches with one side of their contact to +5V
    and the other side the to the D inputs of the latch. A diode comes from each
    of the six switches that combines at the LE pin, and the LE pin is pulled

    The circuit works OK except for one important operation. I need output #1
    to be "high" when the power to the circuit is applied.

    My question is how to preset an input so that output #1 will be "on" with

    Many thanks.
