Abstract:
1. A device comprising: an input circuit receiving first and second input signals, outputting an output signal in response to the first and second input signals and including a first power supply node and a second power supply node; a first power supply line; a first transistor coupled between the first power supply line and the first power supply node of the input circuit and including a first control terminal configured to receive a first control signal, the first control signal changing a level thereof in response to a change in a level of at least one of the first and second input signals and the output signal; a second transistor coupled in parallel to the first transistor between the first power supply line and the first power supply node of the input circuit and including a second control terminal configured to receive a second control signal, the second control signal changing a level thereof independently of each of the first and second input signals and the output signal; a second power supply line; a third transistor coupled between the second power supply line and the second power supply node of the input circuit and including a third control terminal configured to receive a third control signal, the third control signal being relative to the output signal of the input circuit; and a fourth transistor coupled in parallel to the third transistor between the second power supply line and the second power supply node of the input circuit and including a fourth control terminal configured to receive a fourth control signal, the fourth control signal changing irrespective of the first and second input signals; wherein the first power supply line supplies the first power supply node of the input circuit with a first power supply voltage, the second power supply line supplies the second power supply node of the input circuit with a second power supply voltage different from the first power supply voltage.
