Abstract
An integrated circuit includes an input/output pad, an input circuit, and an output circuit. The input circuit is coupled to the input/output pad that receives input signals including a wake-up signal that indicates when the integrated circuit is to switch from a power-down mode to an active mode. The output circuit is coupled to the input/output pad that provides output signals to the input/output pad. The output circuit includes a first P channel transistor in a well having a drain coupled to the input/output pad, and a source coupled to a power supply terminal. The power supply terminal receives a first power supply voltage during the active mode and is decoupled from any power supply during the power-down mode. The well is coupled to the wake-up signal in response to the wake-up signal indicating a change from the power-down mode to the active mode.
