Abstract
A system includes a circuit in a first power domain, a first tri-state inverter having an input coupled to the circuit, and a second tri-state inverter having an input coupled to an output of the first tri-state inverter. The system also includes a level shifter in a second power domain, wherein the level shifter has a first input coupled to the output of the first tri-state inverter and a second input coupled to an output of the second tri-state inverter. The system also includes a shunt switch, a controller, and a pass gate. The shunt switch is coupled between the first input of the level shifter and ground or coupled between the second input of the level shifter and ground. The pass gate is coupled between the controller and the second input of the level shifter or coupled between the controller and the first input of the level shifter.
