I normally read things like this from left to right...
It would be a whole lot easier if you gave us more information about what this. At present I don't know if it's the model number of a TV, or something stamped on an 8 pin chip in a power supply.
What is it, and if it's a part of something, what is it a part of? Perhaps a photo would be helpful too.
A very quick google search suggests it may be a PROM. If this is the case, you'd be advised to try to find a datasheet for it.
Over in the
Datasheets, Schematics, Manuals and Parts there is a sticky thread describing
how to look for datasheets on-line.
It contains some good advice (really!)
This took me a minute or so to find using the basic instructions provided (on the third line...).
