we don't find the mm7317b, but i will try to find the data sheet of ea7317b, we have an entry in our data base to the original data book.
We have to search in our archive and if the info is helpful we will scan the data book.
Please give us a little more time.

Dear Sir,

sorry but we did find the entry in the data book, but it is only a short info, not a useful data sheet.
If we will get further info i will inform you. I will add this entry into the unkown types folder :(
