Thanks.It would be more helpful if you told us what kind of product this is. Active filter, programmable controller, amplifier, etc...? Or what did you disassemble it from?
Thanks.
I have a dozen of these old stock components. Apparently they were never used, and never will be used if I don' t find out how.
Just the manufacturing timestamp, e.g. 8715. You can see they are over 20 years old!no other code or number on these chips?
You may be right. I found some example on the web:It may well be an 'in-house' number, if so there's no way to get information on it.
733W looks like a whole IC family tree!
My experience with obsolete components shows that these companies are only interested in selling their chips. They don' t look very interested in providing datasheets, which they don' t necessarily have. The reason is very simple: if the customer, for example, works out from the datasheets that a 733W02145L1 chip that they sell for $10 can be replaced by a $0.05 LM318N, where is the business for the vendor?definitely true... that was the first thing I realized after a short research.
Why don't you register to one of those sites that come up on google (supposedly still selling these), ask for a sample and datasheet. I'm sure that if they have it in stock, they will send you both for free.

I think you got a point.Vintage electronics hobbyists maybe?
You never know man.. People pay $395 for ugly ass nixie watches. (Don't get me wrong, nixies are kinda cool but it's clunky for a wrist watch and is not worth the cash - personal opinion)
It's a CA3081 NPN transistor array.
Thank you.It's a CA3081 NPN transistor array.
It worked for me! The mystery chip is definitely the CA3081's twin brother.It's a CA3081 NPN transistor array.
