The other way around if either the data line or clock touches the live VCC, it will burn out the LED driver(s) and possibly other components.


While the MOSFET is off, the LED string will be basically floating at Vcc potential. Connecting its data or clock to Vcc at that point should have no effect.

The other side of those signal lines is connected to a live circuit though, ie the AVR which is powered up.  I don't want the possibility of back feeding VCC back into it.
