It's in the archives, multiple times. The only trick is to find one of them.
I started with >time-nuts DS1620 rev<
There is a picture here:
It shows a "D" as part of the date/batch info. I'd guess that's the rev of
the chip. (It's not covered in either of the data sheets that I have.)
These are my opinions, not necessarily my employer's. I hate spam.
