    Can a logic inverter invert a sine wave and/or pulse?
    I built a NOT gate and a NAND gate to try this but neither seem to work. (NAND gate with both inputs being 1)

    Nope.

    A logic inverter inverts logic values 0->1, 1->0.

    If you want to invert a sine wave, build a unity gain, inverting amplifier, or apply a 180° phase shift.

    I would think it would work with square pulse, but you need to see what frequency the chip will work with. If the frequency of the pulses is too fast, then the chip will not do the job you want it to do.

    I built the logic gates with transistors though

    You can use a CMOS inverter biased in the linear region by placing a 1MΩ feedback resistor from the output pin to the input pin.
