Unknown Chip

12/21/2011 6:59 AM

Hi all,

does someone have reliable informations about that shown chip which is sitting in railway equipment formerly built by BBC ? When googling for the name the Chinese say they have thousands of them but no data sheets - so we know they are all faked.

Thanks, regards & happy Christmas for all CR4 fellows and their families

Uwe

TH3071 does not come up in datasheetarchive.com.

Alas, the chip has the appearance of a proprietry firmware memory or application specific IC.

Thats what I fear. I googled for ABB6034 and got the described offers of faked chips. Never saw that logo with the two triangles before.

Can you tell us what the function of the card or circuitry it is involved with at all?

It`s a control card for 110V DC signals decoupled with optocouplers.

Phil D: Yes, but they are a little bit narcotic. The card is an obsolescent product and they are not going to produce more of them. So we have to replace it by an own solution.
