Hi,

They are listed at -

http://www.mouser.com/catalog/615/217.pdf

and NEC have a data sheet on-line if you do a quick Google.

I should point out that they are really only simple dividers
with none of the front-end bits necessary to make a complete
prescaler. I was thinking of using one with an old Racal 1991 VHF
counter that has the built-in maths capability required to enable
a non-decade pre-division.


Cheers - Joe
