I need help to identifying SOIC-8 CI, (marking: 42AD, 2524, M-ADJ.

following up on my post from yesterday regarding the Moog D123-113C control board. I’ve hit a wall with one specific chip. It's a SOIC-8 and the markings are 42AD, 2524, and M-ADJ. I’ve tried looking for those codes but I’m not sure I’m looking at the right datasheets.

Does anyone recognize this part? I’d also love some tips on how to properly decode these markings for future repairs. Thx!

Component identification help: "F T438" and "ON R51 / 13H" from a Moog D123-113C controller

Does anyone know the identification for these specific components found on a Moog D123-113C control board?

Component 1: Stylized "F" logo with the text T438.

Component 2: "ON" logo with the markings R51 and 13H.

The board belongs to an industrial valve control module. I’ve included photos of the components and their location on the PCB for reference.

Any help with the part numbers or datasheets would be appreciated. Thanks!
