VCC Isolation and VCC Disconnect (Ioff-float)

This device has 2 features VCC Isolation and VCC Disconnect which helps in preventing current backflow in case the device is powered down unexpectedly. VCC Isolation occurs when one of the supplies is kept at (or goes to) zero during normal operation, no current will be consumed by the supply that is maintained. This scenario forces all I/Os to be High-Z. VCC Disconnect occurs when one of the supplies is left floating (disconnects) after ramping up, the I/Os are forced into High-Z without consuming any current from the maintained supply. In both cases, the I/Os will enter a high-impedance state when either supply (VCCA or VCCB) is < 100mV or left floating, while the other supply is still connected to the device. See Figure 8-2 for a visual representation.

The maximum supply current is specified by ICCx, while VCCx is floating, in the Electrical Characteristics. The maximum leakage into or out of any input or output pin on the device is specified by Ioff(float) in the Electrical Characteristics.
