The referred thread is from 5 years ago.
The current datasheet is from August 2021.
The datasheet only mentions Top Markings (BJ, BN).
Why did TI not update the Top Markings to all four in the version August 2021 of the datasheet?
Do you not keep a "Datasheet To Do List"?
I had to spend more time searching this thread because I had a Top Marking 4L which did not correspond with the datasheet.
Only thanks to Google not too much time was wasted.
