The image did not attach; you have to use the "Insert"/"Image" menu below the edit box.

The dot at the bottom left indicates pin 1. (The other dots actually are short lines, and are a binary date code.)

Hi Clemens,

Understood.

We would like to know is there any tool or standard format to check the pin 1 marking on top side IC.

Because some IC's have not proper pin 1 marking.

That IC does have proper pin 1 marking; you have to ignore the short lines above/below the text.

Ok clemens.

We come across with pin marking confusion in few more ICs. So we would like to know for the format/TI tool/Datasheet where i can confirm this.

Datasheet we can find but after assembly of components we want to verify pin 1 marking on top of IC.

I will attach the other IC images where we don't have pin 1 marking confirmation on top side of IC after assembly.
