Abstract
PURPOSE:To reduce the energy dissipated as an electromagnetic wave by controlling a driving element by OR between an output voltage threshold value and an input so as to relax the steep change in the output voltage waveform. CONSTITUTION:Threshold circuits 11, 16 having threshold values VT1,VT2 having an output voltage and OR circuits 12, 14 controlling both driving elements 13, 15 are provided. Then the control ON period a2 of the high potential driving element 13 is a period from a change point of an input terminal voltage till an output terminal voltage reaches the VT2 or the like and the control ON period a3 of the low potential driving element 15 is a period from other change point of the input terminal voltage till the output terminal voltage reaches VT1 or over by driving the threshold circuits 11, 16. That is, at the start of rise/fall of the output waveform, both the elements 13, 15 are turned on to apply an intermediate voltage to the output load. Thus, steep change in the output voltage waveform is relaxed.
