PURPOSE:To prevent effectively the malfunction or the like of a circuit and to reduce the power consumption due to a through current by preventing the variance or the like of the earth level due to the through current. CONSTITUTION:The circuit is so controlled that one of two pairs of PMOS transistors TRs T1 and T3 and NMOS TR T2 and T4 are operated when an output level 0 rises from a time t1 to a time t2 or falls from a time tau1 to a time tau2. Consequently, the supplied current is controlled and the output level 0 has a smooth rise or fall characteristic. The other pair of PMOS or NMOS TRs are turned off then. Thus, the evil of flow of the through current is prevented.
