摘要:
A circuit, a multiple power domain circuit, and a method are disclosed. An embodiment is a circuit including an input circuit having a first output and a second output, the input circuit being coupled to a first power supply voltage, and a level-shifting circuit having a first input coupled to the first output of the input circuit and a second input coupled to the second output of the input circuit, the level-shifting circuit being coupled to a second power supply voltage. The circuit further includes a first transistor coupled between a first node of the level-shifting circuit and the second power supply voltage, and a control circuit having an output coupled to a gate of the first transistor, the control circuit being coupled to the second power supply voltage.
