    what's the difference between output push-pull and output open-drain?

    i looked for it, but i didn't find nothing.

    thanks a lot,Isabella

    Hi,

    the difference is:

    -push-pull works 5V when HI state,0V when LOW state

    -open-drain works HI impedance when HI state,0V when LOW state.

    With open drain you cannot drive a 5V output without a pullup resistor.
