PURPOSE:To discharge quickly lots of electric charges stored in a load capacitor or the like being a parasitic capacitor at an output by fitting directly an input transistor (TR) and the 1st reference TR to the output. CONSTITUTION:In the 1st output, >=1 input TRs Q1, Q2, Q3 are fitted and in the 2nd output, the 1st reference TR Q4 is fitted and a full logical amplitude is imposed onto their bases. When the potential of the 1st output terminal O1 changes from a Vh to a Vl, since the electric charge stored in the load capacitor is discharged by input TRs Q1, Q2, Q3 in which the full logical amplitude being Vh-Vl is utilized, the potential is changed quickly. Similarly, the operation above is executed by connecting the 2nd output to the 1st reference TR Q4.
