For our NeoPixel signal to analog LED converter design, we need to convert 3 open drain PWM outputs to drive N-channel sinking MOSFETS. To do that we'll need to invert the signal - but we don't have a ton of space. So let's source a triple-NOT gate that has push-pull output, and can run from 3 or 5V logic. We also want it to be small, but not TOO small!
