SN74LVC1G332: Choosing the footprint created by Ultra Librarian

Part Number: SN74LVC1G332

Hi, guys. The "WEBENCH® CAD/CAE Symbols" is really helpful. I'm using the SN74LVC1G332DBVR to generate 3.3V / 0V signal and I'm creating a custom PCB which will have SN74LVC1G332DBVR.

I'm using EAGLE 9.4 and I noticed from TI's library that

this provides 3 footprint options.

Considering the OR gate I'm purchasing from Mouser, which footprint should I choose?

The WEBENCH® CAD/CAE Symbols web page says (after you've found a part) that

the footprints in the .bxl are available in three sizes per the IPC-7351 standard for the least, nominal, and most real estate on the PCB. The naming convention for the files is as follows:

Name Description

xxxxxx Nominal footprint (nominal packing density)

xxxxxx-L Least footprint (highest packing density)

xxxxxx-M Maximum footprint (lowest packing density)

Oh, I've missed that part. Thanks, Clemens Ladisch. Then, these are options and I only need to choose the preferred size, right?

Like if I have plenty of space for populating, I can choose the"-M Max footprint", right?
