I have a project with 22 20ma 1.7v LEDS.
I was looking to drive them with a 74act244 at 5v with 330ohm drops.
I have seen some circuits that use two outputs per LED. Why ?
Is this just to keep the current throught the '244 low ?
The data sheet for the TI parts claims 200ma total thru the part.
Ideas ? Thoughts ?..know a better way ?
Thanks,
Rusty
