7.5 VCC Isolation and VCC Disconnect

The I/O's enter a high-impedance state when either supply is <100mV or left floating (disconnected), while the other supply is still connected to the device. It is recommended that the I/O's for this device are not driven or kept low before floating (disconnecting) either supply. The maximum leakage into or out of any input or output pin on the device is specified by Ioff in the Electrical Characteristics.
