TMUX4157N: which is the Pin 1

Part Number: TMUX4157N

Hi Greetings!

Please tell us how to identify the pin 1 number of TMUX4157N.

In the datasheet, we could see a circular dot and index area to identify pin 1.

But in reality, we could see on top of the IC, through microscope, only a lengthy line followed by three small parallel lines.

Please direct us which is the pin number of it.

We need to assemble the IC onto our board, awaiting for your reply.

Thanks in advance.

Thanks & Regards,

Indira

Please show an image. I suspect that the longer line is at the left, and that the short lines are a date code.

As shown on p. 22 of the datasheet, the first pin is in quadrant 3.
