Part Search

It actually helps to use a descriptive subject header.

Since I recognize the first number, all you need is the "5089". Of course, that will get a lot of unrelated hits, so toss in "dialer". Those two as keywords for a search engine will turn up lots of hits, some claiming to offer datasheets but maybe not, but various projects that likely do include how to hook up the ic.

For the second, you might try "5098", since that too seems like a familiar number. Either that second one is a variant on it, or just has extra numbers added by a specific company.
