That IC is a timer made by Valvo that can be directly used on mains power and used in an application circuit that has been around for quite some time now.
See
http://electroniq.net/other-projects/uaa3000-timing-circuit-electronic-project.html I am looking for the datasheet for that little beast
Google and usual datasheets websites return nothing.
I have some of those IC's laying around and would like to see what I could use them for.
So, if you have a datasheet for UAA3000, feel free to share.
Thanks
