PROBLEM TO BE SOLVED: To provide a semiconductor circuit capable of preventing current leakage which occurs during standing-by and suppressing an increase in power consumption even if second power is higher than first power when a signal output from a circuit using the first power is entered to a circuit using the second power. SOLUTION: The semiconductor circuit is provided with a first power source circuit using first power VDD1 supplied from the outside, a second power source circuit using second power VDD2 supplied from the outside, and first and second inverters IV1 and IV2 connected between the first and second power source circuits to convert an output signal from the first power source circuit into an input signal to the second power source circuit. When the second power VDD2 is higher than the first power VDD1, during standing-by, the output signal from the first power source circuit is at a low level, and entered to the first inverter IV1.
