if i had 5 devices that needed to use my I2C i could use some these ICs and wire all them up and allow one at a time to use the bus,
but how much can it store and for how long,
is it voltaile?
but then again i keep thinking this is all possible through code...right?
i mean if you have 5 sensors all sharing one data bus, you obviously can only read from one at a time, so you just control which one is on at a certain to then turn it off and then turn on the next one
with some real world applications where they are absolutely needed and cannot be worked around
No because when a sensor has no power it's output looks like a diode thus shorting out the sensor that is turned on.
