Hi Dave!

Yes, it is common on PDIPS to have redundant pin 1 marks on the package.

As to Bev's comment, I thought the "FSC" on the die indicated "Fairchild Semiconductor Corporation".  Do they have a different logo?

It's been awhile so I don't recall.  Is it standard to have both "pin 1"
identifiers on one chip?  It has the notch on the left side as well as a dimple over pin #1. I hope this isn't one of those stupid questions.

But Steve,
There is no remark inside by Fairchild.  And if they realized it at the die stage, there would be no need to redo the outside. My bet is they are counterfeits.

Hi Wayne!

Got your pictures posted, they are here:

It could be that they really aren't counterfeit, but got somehow mis-marked by Fairchild and then re-marked to fix it. But if it is indeed counterfeit, you'd be surprised at what is of value to those that have labor costs at next to nothing...
