Source or Sink?

[UTMonkey]

Hi All,

reading up on an IC which says:-

"This <IC> can source of sink up to 200mA"

By source I am guessing supply a logical high on its output pin of up to 200ma.

What do sink mean?

Thanks

Mark

That may be a 555, just guessing.

Sink means that the chip is grounding it. So you would connect the LED (example) to voltage with a resistor and have the LED's cathode going into the output of the chip.

The picture looks wierd but click on it and view it.

Thats sounds really cool.

Thanks
