Decoder circuit

A decoder circuit which defines selection/non-selection of an object to be controlled with an output signal, the decoder circuit comprising:

• a high voltage imparting portion which imparts a high voltage to a potential setting node;
• a low voltage setting portion which determines presence or absence of a selected state based on an input signal, and forcibly sets the potential setting node to a low voltage lower than the high voltage during the selected state;
• and
• an output signal driving portion which outputs the output signal on a voltage level including the high voltage and the low voltage based on a voltage obtained from the potential setting node,
• wherein the high voltage imparting portion imparts the high voltage via each of first and second switching transistors coupled in series,
• wherein the low voltage setting portion includes a third switching transistor set to a ON state to impart the low voltage to the potential setting node during the selected state, and
• wherein a driving force of the third switching transistor exceeds driving forces of the first and second transistors during the selected state.
