anyone have a datasheet or even just a pinout for tesla MAA501?
i know it's an equivalent to UA709, but i just want to make sure it has the exact same pinout before i start messing with it.

thanks rick!  and for that, i will send you a 709.   ;)
hmmm looks like the pinout is possibly reversed?  a proper datasheet would still help.

How so? Pin for pin it looks all good to me.

MAA501 is the first image with 8-1 going counterclockwise
UA709 is the second image with 8-1 going clockwise
unless they're from different orientations or i'm reading something incorrectly...

???
