In need of a datasheet

[Nightowl]

I have searched and come up empty for a datasheet on a CM0109B TSSOP i.c. 8 legs on each side.
Do you guys have a favorite site for hard to find sheets? Every place I looked said they had it, but the list doesn't show 0109b, just up to 0108.
Thank you

It's a CD40109B:

Thank you. According to the pdf I have the pw0016a. All I could go by was the actual marking on the 3 I removed. I guess I need a whole lot more training to figure out new part numbers? The best part is the pad that lifted off the pcb goes nowhere! I may be able to save this thing yet.
