I have an interface product have some chips carry ST logo, but I can not find anything use the Chip ID. They are EZ026 and EZ030. Can anyone help to identify what is these chips? Here is the picture shows the chip.

Thanks,

Charles

Hello Charles.

Have you ever found any information about EZ026 component?

I also have a damaged board with EZ026 on and I have to replace it.

Thank you very much.

How strongly do you know that the chip isn’t LM311, which ST make in an 8-pin SO-8 package?

The EZO26 could be a date code.

These are not part codes

The markings here are consistent with the LM311 parts

Thank you Danish and Tesla DeLorean.

You both are right. 

I wrongly thought that 311 marking was a date/batch code and eZ026 the part number. 

Now that I know the answer, the question seems to be a little ***... :grinning_face_with_sweat:

Thank you again
