The difference between LS and non-LS package files?

It seems theres are always a LS and a non-LS package file in the custom component folder?

What's the difference between them? What's the usage of LS file?

I've searched in the knowledge base but did't find the explanation about it.

Here you have a diagram where the difference between LS and DIP SYMBOL or packaging symbol is very clear.

a) LS (Logical Symbol) is the one that should be used in the diagrams if you want the circuit to be clear and intelligible, by the coherent arrangement of the function of its pins.

b) Normal or DIP SYMBOL corresponds to the physical distribution of pins on the chip packaging. This symbol is ONLY useful for the development of the printed circuit or its implementation in breadboards, using it in electrical diagrams makes it difficult to understand its functionality.

From the electrical and functional point of view in Simulide both symbols are basically the same, except in the double chip in which things are a bit complicated if their functionality is not separated in the LS.

In simulide, practically all integrated circuits with commercial representation have their double symbol that can be selected by accessing the properties of each one of them.

Great explanation! Thanks!
