Push-pull Output Port

Hi,

What does it means push-pull output port. Is it the same as a normal output port?
If I output a high in push-pull, is it that I get a high? As for outputing a low to get a low at the output?

How many output port normally appear in microcontroller?
1)Open Drain
2)Push-pull
3)????

Please advice and teach.
Thanks.
 

Re: Push-pull Output Port

Pushpull may be wrong term at the microcontroller.
Sink/source capability and pushpull are different models.
But complementery two open drain or collector output known pushpull.

Most comman output types are totem pole, open collektor and active pullup type outputs.

(CMOS and open drain are MOS transistor type outputs.)
