<p>A level shifter has a preliminary level shifting circuit (11) and a final level shifting circuit (12/13) for stepwise changing a voltage range from complementary input signals to complementary output signals, and the preliminary level shifting circuit comprises two complementary inverters (Qp11/Qn12; Qp13/ Qn14) coupled between a constant voltage source (VDD) and a pair of input nodes (14a/ 14b) and controlled by the complementary input signals so that the number of component transistors is decreased. <IMAGE></p> |
