My DTL chips have markings like:
DT uL93659 (Chip type 936)
F 7016
DT uL909759 (Chip type 9097)
F 7013
(I expect 7016 and 7013 are date codes. Not sure what the "59" is about.)
The 59 is the temperature range. For DT?L, 59 is 0C::+75C.

So, what would two chips marked
F? U6A7709393
???? 7043
and
F?? 7306
?7-6987
be?
