As the question says, I need a NOT gate for a simple Bi-Colour LED circuit. I do not want to use an IC with 6 or 7 integrated as I am only going to use 1, so it's just a waste.

So, do individual logic gates exist?

Do they have a specific name?

Note: Just so you know, I'm not looking for shopping advice. I just need to know if a component exists or not. Thanks!


Texas Instruments calls them "Little Logic". They are found in several logic families, included but not limited to 74LVC, 74AHC, and 74AUP. Other manufacturers have similar products, sometimes also available in other families e.g. NXP's 74AXP.

Note that they are strictly surface mount, as those are the most likely targets for such a device.
