CMOS explained??

Hi there. Can anyone offer a comprehensive explanation of how CMOS' work or perhaps recomend a good article or tutorial? I don't know anything about using them. I need to use 2 for an LED Chaser circuit that I am working on for a friend and I would like to have a better understanding of what they do and how thay can be used.

Thanks so much!

You should look up the data sheet of the devices you intend to use. Cmos logic is just a bunch of MOS transistors, this data sheet page may give you an idea.
