    Abstract: Aspects of the disclosure are directed to communications between respective power domains (circuitry) that may operate in a stacked arrangement in which the each domain operates over a different voltage range. A first circuit provides differential outputs that vary between first and second voltage levels, based on transitions of an input signal received from a first one of the power domains. First and second driver circuits are respectively coupled to the first and second differential outputs. A third driver circuit operates with the first and second circuits to level-shift the input signal from the first power domain to an output signal on a second power domain by driving an output circuit at the second voltage level in response to the input signal being at the first voltage level, and driving the output circuit at a third voltage level in response to the input signal being at the second voltage level.

    Abstract: Aspects of this disclosure are directed to level-shifting approaches with communications between respective circuits. As may be implemented in accordance with one or more embodiments characterized herein, a voltage level of communications passed between respective circuits are selectively shifted. Where the respective circuits operate under respective power domains that are shifted in voltage range relative to one another, the voltage level of the communications is shifted. This approach may, for example, facilitate power-savings for stacked circuits in which a low-level voltage of one circuit is provided as a high-level voltage for another circuit. When the respective circuits operate under a common power domain, the communications are passed directly between the respective circuits (e.g., bypassing any level-shifting, and facilitating fast communication).
