National Date Codes? LM308N

[BobPavao]

Hey Pedal guys,

Who can help me with the following National date codes?... Device is LM308N

The codes are as follows;
P142
P145
P146
244A
M8352

I believe at least the P-series is from the 1980s... 1981?...

Thank you,
Bob Pavao

My guess would be the 52nd week of 1983.

Paul,

Yeah that's the easy one.... 

What about the others? Could they be 1981 and 1982?..

Thanks,
Bob

Oh, it's a list of several? Ahem... well then, I would guess 1981 for most of them. Did you check the National data sheet? They might explain the date codes on there - sometimes that information will actually be on the data sheet.
