Hi,
I have this clarification, I have a hardware circuit board and if I am partially powering on the board that is some IC's are powered on and some IC's are not powered ON. what will be the behaviour of these powered off devices, like is there a restriction that on current flow through them? If current flows through some pins without providing the VCC, does the IC get damaged? Just an extension for the same if I have two seperate boards which are connected together and if I power ON one board and power off the other board. What precautions I need to take?
Thanks in advance,
Regards,
Satya
