Looks like some sort of logic/buffer chip. Any markings on it?
Maybe it's a SN74LVC1G04?

That (and the other smaller one on top) is certainly single gate logics.

Figuring out which particular one requires more circuit context or markings of course. Although with pin 1 left unconnected it might be buffers or inverters/NOT.

PS: If you design a board and need buffers/inverters, it might be good idea to tie pin 1 and 2. That way you can potentially simplify your BOM, or expand your part substitution choice when SHTF.
