i don't understand with component dimension from datasheet, such us MAX7301AAX, what is 0.80 BSC mean ?

"0.80 mm BSC" means that the basic spacing between centers (BSC, also called the pin pitch) on that package is 0.80 mm.
 
 
You are not the first person to wonder what that means.

What can you and I do to make things less confusing for the next person?
 
I see that the current

now links to
 
[http://pdfserv.maximintegrated.com/land_patterns/90-0098.PDF SSOP 36 leads footprint pattern],
 
neither of which use "BSC",
 
so perhaps that's already less confusing?
 
The MAX7301AAX is a MAX7301 in a "SSOP" 36 lead package with 0.80 mm pin pitch.
 
The distance between the center of pin 1 and the center of pin 18 is nominally 13.60 mm.
 
 
Confusingly, I see that other manufacturers sell parts in what they call a [http://cds.linear.com/docs/en/packaging/SSOP_36_05-08-1640.pdf 36-lead SSOP package] with 0.65 mm pin pitch.
 
On their SSOP36, the distance between the center of pin 1 and the center of pin 18 is nominally 11.05 mm.

: That sounds great.
 
: A typical footprint library file include dozens of footprints.
 
: So if we have one page per footprint, does that mean we link to the same library file on dozens of different pages?
 
: That seems unnecessarily redundant.
 
: But since no one else has proposed a better organization, let's go with "each footprint gets its own page" for now.
