Help identify IC

(1/3) > >>

giosif:
Hi,

Once again, I am in need of help identifying the IC in the below picture.
Two such components are found in the input section of a bench meter (Gossen Metratop 52) and I'm trying to figure out what they're supposed to do.

Thank you!

May be this?

https://pdf1.alldatasheet.com/datasheet-pdf/view/6768/NEC/UPC4556G2.html

There is a link for the data sheet on that page. Not sure if it is the one.

I was thinking it's a dual mosfet like https://www.onsemi.com/pub/Collateral/NTMD4840N-D.PDF because of pins 2 and 4 could be gates 5 to 8 look like they are on the same wide trace .Could be drain ?

giosif:
Thank you both for looking into this!

I too think it is likely a mosfet, but I'll try to confirm.

andy3055:
Try to trace the pin out/nearby circuitry and then you will get a better idea of what it should be.
