Can anyone identify this IC?

8 pin DIL IC marked
M8448
NMC
9306N
Manufacturer's mark is like two tildes, one above the other.
Google has not been friendly at all with this! =(

Probably NMC9306 datasheet & applicatoin notes - Datasheet Archive.

dc42 is right.

Found with Google image search.

Thanks to both of you. What threw me was that the date code was before the identifier. Thanks again.
