Help identifying IC

mtl777 · 16th May 2008, 05:29 PM

Sorry for this newbie question. I need help identifying an IC in my soundcard that has the following markings:

F PG7AB
MM74HC
74AM

Thanks!

It's difficult to be sure without more information, but the chip is likely to be a 74HC74 TTL dual D fipflop.

yes that's a 74HC74

mtl777 · 17th May 2008, 04:36 AM

Yes that's right.

Thank you so much! I found the complete part # MM74HC74AM at Newark.com. Manufacturer is Fairchild.

I wonder what the PG7AB means?

Thanks again!

Factory code / date code / batch code - any number of
things you don't need to know once you have extracted
the vital "74HC74" out of the mess.
