I'm looking at (among others): http://www.farnell.com/datasheets/3163649.pdf http://www.farnell.com/datasheets/83886.pdf and it strikes me that the pinning or pin configuration is always so that pin 1 is top left, but when presenting the package outline, pin 1 is always at bottom left. Why is that, and what convention is best when doing the footprint ? I have tried to use top left in footprint, but jedec jep95 standards (https://www.jedec.org/category/technology-focus-area/jc-10/registered-outlines-jep95) MO and MS, seems to always be with pin 1 at bottom left. So should I change and also use bottom left for pin 1 ? Regards, /Karl Hammar
