Y-ellow Y'all.
        Though someone will have probably already answered this by the time
this gets posted.

The MC3401 is just another name for the somewhat ubiquidous Quad norton, or
current mode op-amp LM3900.

Any of these part numbers will be the same.
LM2900, LM3900, LM3301 LM3401. Motorola use the same numbers but prefix it
with "MC" instead of "LM" They're common as muck.

I don't know about the other one but perhaps try The Electronic Guide /IC
guide. http://www.bema-electronics.demon.nl/ I'm not entirely sure if that's
the best site as I'm off line at the moment but you could try it.

Hope this helps.

Be absolutely Icebox.
