Abstract:
1. A switching device for coupling an output node to a first node, a second node or a third node, the switching device being controlled by first and second control signals, the switching device comprising: a first circuit connecting the output node with the first node, the first circuit comprising at least a first transistor and a second transistor coupled in series, the second transistor being controlled by a third control signal; a second circuit connecting the output node with the second node, the second circuit comprising at least a third transistor and a fourth transistor, the third transistor being controlled by a fourth control signal and the fourth transistor being controlled by a fifth control signal; a third circuit connecting the output node with the third node, the third circuit comprising at least a fifth transistor and a sixth transistor, the fifth transistor being controlled by a sixth control signal; a fourth circuit generating the third and fourth control signals from the first control signal, the third and fourth control signals being generated so as to be mutually exclusive; a fifth circuit receiving the second, fifth and sixth control signals and generating first and second logical control information; a first translator block receiving the first logical control information and generating the sixth control signal; and a second translator block receiving the second logical control information and generating the fifth control signal.
