IRS25752 IC has no pin 1 marker

[treez]

Hi
I just bought two pieces of the IRS25752 IC from Farnell and its got no pin 1 marker.
Do you know how i can tell which is pin1?

There is lettering on top and i wonder if one is viewing this lettering from the right way up, then its on the left/right?

(The lettering says "5ND1")

I have viewed the chip surface from all angles and there is no marker for pin 1

Hi,

Let's see a picture of the IC.

The datasheet indicates to me that you are left to use
the lot / date code on the top, or the mfr logo on the
bottom, to orient yourself. See Pg 11.
