Hello,

I have a question for LM393-N DSBA package(LM393TLX/NOPB).

The below is from Mechanical data in the datasheet.

Is there any mark on the top of the package to indicate BUMP A1 Corner?

Regards,

Oba

Helo Oba,

Yes. There is a laser-mark dot or a "1" in the corner.

Hello Oba,

The actual mark will differ depending on the assembly site (for former National devices).

Please see AN-1112, page 20

Some TI devices will have a "1" as the pin 1 mark.
