I've gone through leftover parts from a 2005-6 project and four I can't ID. They are
52A9TK9 242GC Ti, TO-92 pkg
JR38AD ADC, DIP-8 pkg
JR48AC ADC, DIP-8 pkg
JR49AG LMC 64, DIP-8 pkg

Seems odd these would disappear from the Google memory this soon.

Can anyone help me?

Thanks,
Andyh

Hello,

It can well be that the parts are propriarity parts.( inhouse codes ).
They are likely specialy made for one project.
You will not find the datasheet for them.
