Alberto,

The datasheet writes about a "typical switch time" of 20nS.

If you have in your junk box, by all means - use it but! Don't break your neck 
and replace the currently used switched with the SA one as it's "just another 
switch" and not really an improvement.

If you want a fast one, use the suggested FSAV332 chip from fairchild. It 
looks that it's as good as it gets ( currently! ) but as someone wrote 
earlier - "In AD we trust!" If there are anyone on the mil market with the 
need for faster switches, I'm sure AD will create one to fill that market 
segment.

Another solution is of course if anyone of us all that might work for the 
little green men or - even for a telco with a R&D budget left, starts 
designing a really fast gidgy gadget that includes this kind of QSD... One 
can also hope the "plumbing department" comes up with a really neat chip as 
well...
