Totem Pole Circuit Operation. Totem pole push pull output stages two matched transistors of the same polarity can be arranged to supply opposite halves of each cycle without the need for an output transformer although in doing so the driver circuit often is asymmetric and one transistor will be used in a common emitter configuration while the other is used as an emitter. Of course totem pole output stages are also possible in both nor and or ttl logic circuits.
For example you want to drive gate of mosfet with the help of microcontroller output pin the microcontroller output pin is generating a square wave of voltage level 5 volt and to fully drive mosfet gate of p channel mosfet you need to provide 12 volt at the gate of p channel mosfet. Of course totem pole output stages are also possible in both nor and or ttl logic circuits.

Totem pole basically an output driver circuit use to convert one level of voltage into another level of voltage. Many ics use totem pole outputs in fact it s so common that the output structure isn t mentioned in the data sheet title. Of course totem pole output stages are also possible in both nor and or ttl logic circuits.
