1. A level shift circuit, comprising:
a first power supply line to which a first voltage is supplied; a second power supply line to which a second voltage that is higher than the first voltage is supplied; a third power supply line to which a third voltage that is higher than the second voltage is supplied; a fourth power supply line to which a fourth voltage that is higher than the first voltage and lower than the third voltage is supplied; an input circuit to which voltages are supplied from the first and second power supply lines, and which is configured to receive an input signal; first and second signal paths that are connected in parallel between the first power supply line and the third power supply line; first and second switching elements configured to control conduction of the first and second signal paths, respectively, based on the input signal that the input circuit receives; first and second diodes provided on the first and second signal paths, respectively, at positions that are on a side of the third power supply line with respect to the first and second switching elements; a cross-coupled circuit configured to make one of a first node which is located on the first path at a position that is on the side of the third power supply line with respect to the first diode and a second node which is located on the second path at a position that is on the side of the third power supply line with respect to the second diode a high level and make the other of the first node and the second node a low level, and that is provided on the first and second signal paths at a position that is on the side of the third power supply line with respect to the first and second nodes; and an output circuit to which voltages are supplied from the third and fourth power supply lines, and which is configured to output an output signal based on at least one of a signal appearing at the first node and a signal appearing at the second node. |
