It is always helpful to have sufficient information for a meaningful answer. In this case, a clearly legible photo of the part in question is missing. Can you please upload it?

You can see from this that a photo is always very important: it is an SO-8 package that has eight pins instead of four. The device in question is an LM211D.

Good luck!
