ABSTRACT:
A system and method for controlling an input/output driver. The system includes a control system configured to receive a first supply voltage and a second supply voltage and generate a control signal, and a first transistor including a first gate, a first terminal, and a second terminal. The first gate is configured to receive the control signal, and the first terminal is configured to receive the first supply voltage. Additionally, the system includes a second transistor including a second gate, a third terminal, and a fourth terminal, and the second gate is coupled to the second terminal. Moreover, the system includes a third transistor including a third gate, a fifth terminal, and a sixth terminal, and the third gate is configured to receive the control signal. Also, the system includes an input/output pad coupled to the fourth terminal and the fifth terminal.
