Patent ID: 8384433

Claim:
A semiconductor device comprising: a first inverter that receives an input signal to output an inverted signal; a second inverter that receives the inverted signal to output a first output signal; and a third inverter that receives the input signal to output a second output signal by using the inverted signal as a power supply, wherein the first inverter includes a first one conductivity type transistor and a first opposite conductivity type transistor that are connected in series between first and second power supplies and to whose control electrodes the input signal is commonly supplied, the second inverter includes: a second one conductivity type transistor and a second opposite conductivity type transistor that are connected in series and to whose control electrodes the inverted signal is commonly supplied; a third one conductivity type transistor that is connected between the first power supply and the second one conductivity type transistor; and a third opposite conductivity type transistor that is connected between the second power supply and the second opposite conductivity type transistor, and the third inverter includes a fourth one conductivity type transistor and a fourth opposite conductivity type transistor, whose power supply terminals are commonly connected to an output terminal of the first inverter and to whose control electrodes the input signal is commonly supplied.
