      On the last delivery of the subject components the "Dot" representing Pin 1 appears on the lower left side

      instead of the upper left side while the printing text is left to right (see picture).

       

       

      Who may advise on Where is the real Pin 1 ???

          Hi,

           

          As a simple check, assume that the dot is at right place and use a multimeter to check the connection between ground pins. From this you will get to know whether the dot is at right place. From the below image you can try finding short between Pin 14, Pin 38, Pin 66 and Pin 87.

           

          Please update if you found the dot convention is wrong.

            HI Ganesh

             

            Thanks for your suggestion which helped me to establish the fact that the dot represents Pin 1,

            which is on the lower left corner.
