8.3.4 VCC Isolation and VCC Disconnect
The outputs for this device disable and enter a high-impedance state when either supply is <100 mV or left floating (disconnected), with the complementary supply within the recommended operating conditions. It is recommended to keep the inputs low before floating (disconnecting) either supply.
The ICCx(floating) in the Electrical Characteristics specifies the maximum supply current. The Ioff(float) in the Electrical Characteristics specifies the maximum leakage into or out of any input or output pin on the device.
