An integrated circuit includes at least one output cell including a first output cell having a ground pin connected to a ground rail, a first power supply pin connected to a first power rail, a second power supply pin connected to a second power rail, a data pin, at least one voltage select pin, and an output pin wired to the first output pad. The first output cell is configured to operate according to a first mode wherein the output pin has a first voltage amplitude, and according to a second mode wherein the output pin has a second voltage amplitude larger than the first voltage amplitude depending on a control signal applied to the at least one voltage select pin.
