Do I understand the operation of the MAX4896 chip correctly?

Question

Iron

I re-read the MAX4896 datasheet several times, until I understood everything ... it’s clear how to control it, but it’s not entirely clear what exactly it opens?
That is, it is written that if the OUT[0-7] pin is active, then it is connected to PGND, and if not, then it goes like Z.
Is it possible to connect power + to PGND, and connect devices to OUT pins that will have to receive food or not?
Here there are 8 devices of 5v each, and here just 8 pins are ideal, it’s not clear just where to throw the common plus .... maybe I misunderstood the essence of the chip? It turns out that all 8 negative power outputs of the devices are twisted together and connected to - power, and the pluses are thrown through the chip and PGND to the power plus ...?

Answer 1

Connect all minuses supplying controlled devices to PGND, connect controlled devices on one side to the pluses of their sources and on the other side to OUT[0-7].
No, because current in OUT[0-7] can only flow in.
