LM347 comparator/op-amp

[erictham83]

Can anyone send me LM347 comparator/op-amp datasheet from national semiconductor or provide me more details?
i had search over google but i can find this. It seem like discontinue item.

I can't find it, it might be similar to the LM348.

I don't recall National ever making an LM347. Where did you get this number? Perhaps it is a typographical error.

I suspect our OP is looking for **broken link removed**, a quad op amp.

It is the same.

LM347 is the same as LF347? I don't think so. Can you find a datasheet for LM347?

 

[hotwaterwizard]

Nope Just Proof they are the same.

Good sleuthing, John.
In the National LF147 datasheet you posted, I saw one reference to LM147 for a specific ceramic-packaged part. You found enough other references to convince me that one or more companies produced parts labeled LM347. It's curious that none of them apparently produced a datasheet under that part number.
