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.
