Abstract: PURPOSE: To minimize a bad influence of voltage transition by controlling the bias, which is applied to a transistor whose output is connected to a circuit earth terminal, by an earth repellent circuit and limiting the operation of the earth repellent circuit except in a high-low transition stage. CONSTITUTION: A power saving circuit 50 limits the operation of an earth repellent circuit 34 to such state that the output is in the high state and IN2 goes to the high state to switch the output to the low state. A NAND gate included in a circuit 50 has an input 52 connected to the circuit output and connected to the gate of a transistor TR 14. When both inputs are in the high state, a TR 40 of a circuit 34 is operated to operate a TR 42. TRs 40 and 42 are not operated in all other states of the buffer circuit. Thus, they are operated only in the output transition state from the high level to the low level to save the power.
