What are “totem-pole” outputs? Those are simply “fully buffered” outputs where an input signal is converted so that logic one is a path to the positive voltage source, and logic zero is a path to ground. As opposed to “open collector” or “open drain” logic where logic level zero is simply left “floating.” And a buffer is also a “push-pull amplifier.”
