Bosch kts 300

[mk1]

I have come by a bosch KTS300 hand held scan tool  .
The problem is it has a fault  .
Took it apart and there is a ic chip that is damaged, I am looking for some help locating a replacement. Have done the usual Google, RS and Maplin search with no luck. The no's on the chip are...
305A
W993A9535
ST  
Any help please, Steve.

Steve,  I am going to the U.S. for a week starting next sunday and If I know there is a big radio shack store near where I'll be. I'd be happy to pick one up for you if they have one. If i remember right about all they stock is analog I/C's and 555 timer chips. Been a while since I've been there though. 305A is the commen number for it where as W993A9535 should be the vendors part number.  I think ST is the type of chip. (and,or,nor gate ) Thats about all I remember from digital electronics and advanced circuitry. Been 5 years since I took those courses so I could be wrong. lol.

Thanks, if you find something that you think will do the job just get it and I will post the cash to you .
If it is wrong or doesn't work, my problem. (hope the chip isn't dear ).

More info, the chip is a ST part no: L9305A.
RS list it but it is a discontinued part, anyone able to cross reference this no to a current ome, thanks.
Steve.
