Thanks,

You did not mention if this is NOPB, or not.

To get to these locations from the ti.com product pages you would click on the red 'Sample & Buy' button. That will take you to the National Semiconductor Product Folder for that device, where you click on the 'Packaging' tab on the left of the page, find your packaging option in the list and then click on 'Details' in the RoHS Status column.

Or, go straight to this page, and search for the part number (i.e. NSID):
