Integrated circuit device

An integrated circuit device comprising:

• an input terminal;
• an output terminal;
• a first power supply line;
• a second power supply line configured to transmit a voltage lower than a voltage on the first power supply line;
• a first transistor having a gate electrically connected to the input terminal;
• a first resistance element electrically connected between one end of the first transistor and the first power supply line;
• a second resistance element electrically connected between the other end of the first transistor and the second power supply line;
• a second transistor having a gate electrically connected to a first node between the first transistor and the first resistance element, and one end thereof electrically connected to the first power supply line;
• a current source electrically connected between the other end of the second transistor and the second power supply line;
• and
• an inverter circuit having an input part electrically connected to a second node between the second transistor and the current source, having an output part electrically connected to the output terminal, and configured to output a voltage on any of the first power supply line or the second power supply line from the output terminal.
