Abstract
A voltage-switching device includes a high-voltage translator connected to a high-voltage node receiving either a low-voltage logic level or a high-voltage level as a function of a low-voltage/high-voltage mode control signal to provide at least one output signal as a function of this mode control signal and of a switching control signal. A voltage-level switching circuit is controlled by output signals from the high-voltage translator and by the mode control signal and the switching control signal for application, as output voltage levels, of either ground or the low-voltage logic level in low-voltage mode or the high-voltage level in high-voltage mode.
