I would like to pass the output of an LT1413CN8 op-amp through a 2-pin red/green LED (looks white when off) and back to it's inverted input.

In Multisim, there is a red/green LED option but that is a 3-pin configuration. If I drag and drop a green LED and red LED from the component menu, wire them up tail to head, and transfer the design to Ultiboard, 2 separate LEDs and their footprints appear (which is expected.)

Is there anyway to build a custom component made up of those 2 LEDs, but with only 2 pins and 1 footprint?

Or, is there a component that I am not seeing in the component menu that solves this issue?

Or, is there a recently-updated library with this part? I am using Multisim 14.1

Thank you.

The 3 pin red/green is called common cathode.
A 2 pin with red OR green is a bidirectional LED e.g. Kingbright WP937EGW
Then there is an LED with both red and green in the same package e.g. Marktech Optoelectronics MT2030-HRG-A

A red green in the same package has the same model as any other LED.

If looking for a bidirectional then search for "bidirectional LED".
