What is it?

I'm a newbie and have decided to take up electronics in my retirement. I know ohms law and took a soldering course for PCB including SMD's. I've been playing with LED's to start with, but built a couple power supplies and PWM's. One from schematic alone and the rest from kits.

OK, my thread... Integrated Circuits! I've been getting a "grab bag" of IC's from a local salvage place and have several examples of one, I can't find any data on. It's marked "U 244b" and is an 8 pin package. Most Google references are not in English.
