I have an old TI Digital alarm clock chip from 1989 (TMS3455NL-R) and i can't find a datasheet anywhere on the web for this variant. I believe that it has a different pin-out from the TMS3450NL. I would like to know if it is possible for me to get a copy of the datasheet as I am building a digital clock based around this part.
The chip can be seen here: i.imgur.com/fXZ7VmV.jpg
