Level-shifting device
Abstract:
A voltage level shifting device for driving a capacitive load has an input terminal for receiving a first input signal switchable between a first logic state corresponding to a first reference voltage and a second logic state corresponding to a second reference voltage, and an output terminal for supplying an output signal switchable between a first logic state corresponding to a third reference voltage and a second logic state corresponding to a fourth reference voltage. The device also has a first electronic circuit that is activated following a commutation of the first input signal from the first reference voltage to the second reference voltage for fixing the output terminal to the fourth reference voltage. The device further has a second electronic circuit that is activated following a commutation of the first input signal from the second reference voltage to the first reference voltage.
