Abstract
A semiconductor integrated circuit includes a first voltage supply unit, a second voltage supply unit configured to supply a voltage with a level different from that of the first voltage supply unit, and a voltage stabilizing unit connected between the first and second voltage supply units, and including at least one discharge path that includes a clamping section configured to temporarily drop a level of a voltage introduced from the first or second voltage supply unit, and a discharge section configured to discharge the voltage having passed through the clamping section to the second or first voltage supply unit.

A semiconductor integrated circuit comprising:
- a first voltage supply unit configured to supply a voltage with a first level;
- a second voltage supply unit configured to supply a voltage with a second level different from the first level;
- and
- a voltage stabilizing unit connected between the first and second voltage supply units, and including at least one discharge path that includes a clamping section configured to temporarily drop a level of a voltage introduced from the first or second voltage supply unit;
- and
- a discharge section configured to discharge the voltage that is introduced from the first or second voltage supply unit from the clamping section to a ground terminal.
A semiconductor integrated circuit comprising:
- a first discharge path connected between a first voltage supply unit, configured to supply a voltage with a first level, and a second voltage supply unit, configured to supply a voltage with a second level different from the first level, the first discharge path including a first forward diode, connected to the first voltage supply unit, and a first reverse diode, connected between the forward diode and the second voltage supply unit;
- and
- a second discharge path connected between the second voltage supply unit and the first voltage supply unit, the second discharge path including a second forward diode, connected to the second voltage supply unit, and a second reverse diode, connected between the second forward diode and the first voltage supply unit;
- wherein the first forward diode and the second forward diode are configured to temporarily drop a level of a voltage introduced from an input node, and
- wherein the first reverse diode and the second reverse diode are configured to discharge a voltage that is discharged from the first forward diode or the second forward diode to a ground terminal.
