i have been reluctant with details as i have been away from my desk. however, now I have it and a multimeter right in front of me.
It appears as though the 7th lead is an open circuit to the rest of them. I must have bridged a connection before.
perhaps it is only there since the package width is as wide as seven 0.1" leads and not six? just a simple "NC" deal on the datasheet i presume, if I could find one (no part number)
Thanks for the help anyways, it appears to be a moot point. :/
