These LEDs are three leaded bi-colour light sources which are suitable for a variety of applications where dual state illumination is required in the same package. They contain two LED chips which are mounted on a central common cathode lead. This allows for maximum on-axis viewability. Colours between the chips can be generated by independantly pulse width modulating the LED chips.
