Abstract
Switching circuit comprising a reference voltage, an input voltage, suitable to assume alternatively a negative value or a value equal to said reference voltage, an output node, suitable to assume selectively three possible voltage values equal to a supply voltage, to the reference voltage, to the input voltage or, alternatively, to be kept floating, in response to a first, a second, a third, a fourth, a fifth, a sixth control logic signal, switching between the supply voltage and the reference voltage.
