Hello,

Full PN: SN74AVC2T245RSWR

I need the top marking document to identify Pin 1 location as I am trying to understand which one is the orientation dot, and what's the other dot-pattern meanings? we have different dot-pattern on 2 projects, and one part has a mysterious short

Thanks,

Quynh

The short bars above and below the text are a binary date code.

The physical parts actually have 4-dots in total (see attached doc) and located in different locations. We need to confirm if locations of dots are matter??

Thanks,

Quynh

Hello Quynh,

For RSW packages, there will be a notch on one of the pins that indicate pin 1 orientation.

Regards,

Josh
