Report Could some one please explain to me how a DRL...? Wait! one more thing! in Theory articles Posted November 27, 2006 There where actual incidents last year where I needed to run LEDs from some OR and AND gates. Because LEDs run off of such a low current, the current running out of the "low" DRL gates was enough to turn them on.DRL isn't the only option for making these gates. It was the most appealing because it was fast to build, not that I understood what I built... TTL was a big turn off because I don't know much about transistors and I defenently don't want to deal with multi emitter transistors...So, Is there a way to run LEDs properly from a DRL gates?
