My long awaited SN7407N's arrived today by priority USPS First Class mail.

I thought the package was empty. I could not feel the DIPS.

They are D package. I did not know this size dip existed. I can barely see the individual pins. They do not fit into any of my .100" grid prototype boards.

I think I need to specify J or N. Is there a difference from the prototyping point of view?
