PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit capable of maintaining characteristics of transistors in a circuit in which a plurality of the transistors are cascaded. SOLUTION: An inverter circuit 1 includes P-type MOS transistors 10, 11 and two N-type MOS transistors 12, 13 connected in series. The P-type transistor 10 is connected to a high-potential power source V<SB>H</SB>, and the N-type MOS transistor 13 is connected to a low-potential power source V<SB>L</SB>. Gates of the MOS transistors 10-13 are connected to an input signal line 19. Furthermore, the inverter circuit 1 includes a P-type MOS transistor 17 connecting a node 14 of the P-type MOS transistors 10 and 11 and the input signal line 19, and an N-type MOS transistor 18 connecting a node 15 of the N-type transistors 12 and 13 and the input signal line 19. Gates of the P-type MOS transistor 17 and the N-type MOS transistor 18 are connected to an output signal line 20 of the inverter circuit 1. COPYRIGHT: (C)2009,JPO&INPIT
