I'm looking for Datasheet of a TI vacuum fluorescent display driver, TL4180AN, wich is obsolete. Ti.com do not have the datasheet, maybe because it's only exist in a paper version... No idea of the year of the conception of this circuit,(fab in 94?) i have found it on the operating panel of an old photocopier. I think it would be interesting to use the 40 character VFD on it .
