Totem pole symbol?

Postby Solar Granulation » Fri Jan 23, 2015 4:39 pm

Although it's not of dire importance I'd like to illustrate in my schematic that the circuit must be connected to a totem pole pin (such as on an LED driver). Is there a symbol for totem pole outputs?

To my knowledge, there isn't a simple single electronic symbol for a totem-pole output circuit.

In that case, would it be acceptable to create a symbol? I think it would help clarify my schematic, which I do I intend to share with others.

If I were going to create a symbol for that, I would make a block with a input, the stacked totem pole transistors image as in the attached, an output, and power supply connections as needed.
