An integrated circuit includes a core-logic providing a core-logic output, a latch in communication with the core-logic to store a state of the core-logic output, and an isolation circuit for selectively interconnecting the core-logic output to an input of the latch. The circuit also includes and a power consumption controller in communication with the core-logic, the latch and the isolation circuit, for controlling the latch to store a state of the core-logic output, and output a corresponding signal. The controller is further operable to signal the isolation circuit to isolate the core-logic output from the latch by providing an output corresponding to predetermined value and transition the core-logic from a high power state and a low power state. This prevents transient signals from propagating to interconnected circuit blocks and external devices.
