The first one I pulled up at Mouser had a minimum order of 750.
I see a selection criterion of PDIP-6 with Gull Wing
. I've not seen that term before. Sounds like a heat sink but obviously not for this part. Do you know what that is about?
I saw the part at your other link. I found a few other places too. I may have to try one of them to see if I can get a hobby stock of those parts.
But definitely, I need to get at least one soon to experiment with. I feel a Mouser order coming on. My wish list is buldging there.
