摘要： A voltage shifter has a supply line receiving a supply voltage that varies between a first operating value in a first operating condition and a second high operating value, in a second operating condition. A latch stage is connected to an output branch and to a selection circuit, which receives a selection signal that controls switching of the latch stage. The latch stage is coupled to the supply line and to a reference potential line, which receives a reference voltage that can vary between a first reference value, when the supply voltage has the first operating value, and a second reference value, higher than the first reference value, when the supply voltage has the second operating value. An uncoupling stage is arranged between the latch stage and the selection circuit and uncouples them in the second operating condition, when the supply voltage and the reference voltage are at their second, high, value.
