    Could I accomplish the same thing as the CD4093 IC if I used 4 single NAND
    gates? In other words, if this chip is just 4 NAND gates, why does it need
    to be connected to power and ground?
     
  2. A 4093 has schmitt trigger inputs, which makes it different from an average
    nand gate. If it's specified, or there is a need for a schmitt trigger
    input, then the results will suffer or not work at all if you use something
    without schmitt trigger inputs.

    You also will have a hard time finding single nand gates. Oh, I gather
    there may be some, but generally you'll need more than one so it makes
    little sense to only put one in a package, the cost of adding the other
    three will likely be less than the cost of the packaging.

    I don't know where you're going with the power bit. Any gate will need
    power.
