... Due to the SCR structure inherent in the CMOS process, connecting any terminal to voltages greater than V cause destructive device latchup. For this reason recommended that no inputs from external sources not operating on the same power supply be applied to the device before its supply is established, and that in multiple supply systems, the supply to the ICM7211 and ICM7212 be turned on first. ...
