    • When an input signal (IN) having the amplitude of a first power supply voltage (VDD1) is inputted to the gate terminal of a PMOS transistor (PM51) operating on a second power supply voltage (VDD2) higher than the first power supply voltage, a level conversion is performed by PMOS transistors (PM1 through PM4). The source terminals of the transistors (PM1, PM3) and those of the transistors (PM2, PM4) are connected to the first and second power supply voltages, respectively, while the gate terminal of the transistor (PM4) is connected to the drain terminals of the transistors (PM1, PM2). The gate terminal of the transistor (PM2) is connected to the drain terminals of the transistors (PM3, PM4). The input signal (IN) and the inverted version thereof are inputted to the gate terminals of the transistors (PM2, PM1), respectively. The amplitude of the input signal (IN) between a reference voltage (VSS) and the first power supply voltage (VDD1) is level converted to the amplitude between the first and second power supply voltages and outputted from the transistors (PM1, PM2), thereby causing the transistor (PM51) to be conductive.
    • 当具有第一电源电压(VDD1)的振幅的输入信号(IN)被输入到在高于第一电源电压的第二电源电压(VDD2)下工作的PMOS晶体管(PM51)的栅极端子时, 由PMOS晶体管(PM1至PM4)执行电平转换。 晶体管(PM1,PM3)的源极端子和晶体管(PM2,PM4)的源极端子分别连接到第一和第二电源电压,而晶体管(PM4)的栅极端子连接到漏极端子 的晶体管(PM1,PM2)。 晶体管(PM2)的栅极端子连接到晶体管(PM3,PM4)的漏极端子。 输入信号(IN)及其反相形式分别输入到晶体管(PM2,PM1)的栅极端子。 参考电压(VSS)和第一电源电压(VDD1)之间的输入信号(IN)的幅度被电平转换为第一和第二电源电压之间的幅度并从晶体管(PM1,PM2)输出, 从而使晶体管(PM51)导通。
