Hello, I was wondering if there are any multi-color/ bi-color leds that have 2 cathodes and 1 anode. I am working on a project and I want to use 1 multi-color led, but the IC's pins go to ground. I am using 2 pins on the IC ( UCS1001-2-BP-TR ) that show attach detection and/or an error. All of the leds available seem to only have 1 cathode and 2 or more anodes. Is it possible to make a single LED with 2 or more cathodes and 1 anode? (if it is possible, im trying to get through hole parts not SMD, but any info will help ) This is the kind of led i'm looking at, but this one only has a single cathode/common. http://optoelectronics.liteon.com/upload/download/DS20-2001-645/S_110_LTL1BEKVJNN.pdf |

All of the 3-pin bi-colour LEDs I've used were common cathode. The Digikey parametric search doesn't have a CA / CC selection which is ominous. You can definitely get RGB LEDs in CA or CC though. Maybe that's near enough for your needs? |

In addition to the above suggestions (which are good ones), what about using a dual transistor in a small SOT23 (or smaller) package to switch your CC LED with a pair of grounds from your chip? Do you have enough board space for another SOT package? |

I found this Lumex part: SML-LX15IGC-TR, red/green, common anode |
