Abstract
A level shifter includes a first and a second transistor coupled to a first power supply voltage terminal supplied with a second power supply voltage in parallel, a third and a fourth transistor coupled to a reference voltage terminal in parallel, a first and a second depression transistor, the first depression transistor being coupled between the first and the third transistor, and a timing control unit placed between a second power supply voltage terminal supplied with a second power supply voltage lower than the first power supply voltage and the reference voltage terminal, that generates the first control signal and the third control signal different from the first control signal corresponding to an inverted signal of an input signal, and generates the second control signal and the fourth control signal different from the second control signal corresponding to a non-inverted signal of the input signal.
