Hello,
In RS-485 bus architecture if a node (DS16F95QML-SP) is powered off, is there any risk about the component whether it can be damaged or not due to other powered nodes in the bus? And also, is there any possibility that an unpowered DS16F95QML-SP in RS-485 bus can cause any abnormality on an unpowered board such as voltage increase on its VCC pin (normally should be at ~0V)? If possible, could you please share the output stage of DS16F95QML-SP to be able to check the protection options?
Regards,
