I'm trying to recycle a keypad and need help identifying a chip on the board.

There are only 2 numbers on the chip and I can't seem to find out what it does.

The other option is that I bypass the chip and just use the voltage divider circuit but I'm not 100% sure how that would work with my Arduino.

Would love any advice, photos of the board attached..

Cheers

Phil
