I have two ICs and I need to discover them. I've searched for the marking on top of them, but I didn't have success. I've tried some tools on the internet (this forum included), also nothing. I used google advanced search tools, combining packages and nothing.
Infos that i got from IC 1:
IB2 or 1B2 (it's not clear)
On the pin 1 circle it has a "33J" engraved
Infos that i got from IC 2:
