Anyone come across some 8212's with any strange markings.
I bought these a long time ago, so I can't recall which parts supplier had them.
The part# is 8212P but it has no vendor symbol or prefix
And the datecode has TSL9445
I didn't think they were still made 20yrs later
​And the prefix on the datecode is rather odd​, there's a "TSL"
I also thought the datecode was the part# and the 8212P was the datecode.
But I would be really mad at the parts supplier if they sold them this way.
I just might have to add this profile to my chip tester to see if these are really genuine

My guess is that the Manufacturer was TSL, the date code 9445 (date code could be 1994, 45 week pr 1995, 44th week?), and the parts is a 8212P (P as in plastic package?)
