put finger to keyboard and composed:

I'm trying to identify an SMD on a PC board with some SPST keypad switches.
It has 4 terminals and is marked M1I. Each is labeled DA1, DA2, etc. on
the silkscreen, and two of the four terminals are marked A and K. All four
terminals connect off in different destinations. I'm guessing this is some
sort of debouncer or logic-level-shifter? But I'd like to know, if anyone
has any suggestions.

Diode array? (A)node/(K)athode?
