<P>PROBLEM TO BE SOLVED: To provide a driver circuit for establishing a high speed operation and low power consumption. <P>SOLUTION: This driver circuit for inputting a logical signal X with a low potential side power source as a reference, and for generating a logical signal Y by using a high potential side power source Vcc is configured of a level shift circuit 10, an output circuit 20, a first detection control circuit 30, and a second detection control circuit 40. In this case, a pull-down circuit 21 and transistors Q11 and Q21 are complementarily driven to be turned on/off by a logical signal X to be inputted to the level shift circuit 10 and an inverted logical signal X<SP>*</SP>, and drain currents I1 flowing to a driving circuit 11 are controlled based on a control signal out1 from the first detection control circuit 30, and drain currents I2 flowing to a pull-down circuit 21 are controlled based on a control signal out2 from the second detection control circuit 40. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
