So I'm trying to use a (actually five of them ) CAY16 resistor array in my PCB.
The schematic shows pins 1, 6, 7, and 8 to be all connected. But the footprint shows thar pins 5, 6, 7, and 8 should be the ones that are connected, because in the PCB, it looks like pins 4 and 5 aren't correct. And there is no ratline joining pins 1, 6, 7, and 8 together like there are in other symbols that have connected pins.
The logical implication that I got from the datasheet was that KiCAD is completely incorrect, but the datasheet doesn't actuallt specify.
The schematic symbol in the datasheet implies that it should work just the same as if I got four resistors and glued them together. The datasheet does not include an actual pinout, which is a shame.

I actually don't have any of these and haven't used them before, so I can't check them...
I was hoping to avoid having to buy any specifically for that as I was trying to be lazy and get the company making the PCB to assemble all the SMD components...
Maybe I'll go with a better documented array, or I'll just buy some, unless someone with experience can help further/has one they could test if they wanted to. I suppose I could also pull one off my burned out SMD Uno too...
The first picture in the PDF file gives a good hint.
Using an LED and eventually an additional serie resistor You can find out. It looks quite clear that the resistors are connected between pin 1 and 8, 2 and 7, 3 and 6, 4 and 5.
Marking pin 1 in the upper left corner is an old standard. (Your first picture)
Buy Yourself a multimeter! Working with electronic circuits without a meter is like being a soldier without weapons. There are plenty of good low cost multimeters.
