IC1 Question

[EVIL1954]

I read in a previous thread where someone was having trouble with IC1 ICL7660 not having the letter A in it's code . This would depict a 12V version of the IC. Unfortunatly I perchasted a ICL7660cbaz which I think is the 10 V model? Now my question .As my project is a SMD version and will only ever be run with a 9V battery will a 10V ICL7660 matter. HELLP!

If you plan to run off a 9V battery then it doesn't matter.
