I essentially need the opposite of a NOT gate. I know that sounds silly, but what I'm really looking for is something that will provide the current based on the signal sent to it so that the more sensitive circuitry sending the signal doesn't have to run higher current levels. I've found I could do this using two NOT gates in a row or an AND gate and just using both the inputs on the AND gate to be the same, but I'm guessing there must be a circuit piece already built for this. One that I can provide a signal and supply voltage to and it will provide the output current. For what I'm doing the signal voltage and supply voltage need not be the same. I just need to make sure the circuitry sending the signal doesn't have to send the higher current with the signal itself. Thanks!
