Abstract

PURPOSE:To prevent short circuit current from being generated, by providing the input circuit of an FF circuit producing two change-over signals with phase different from reference square wave by 180 degrees, with a time constant circuit. CONSTITUTION:From a T type FF circuit 11, based on the output of a reference pulse generating circuit 10, the output of change-over signals A and B with phase different by 180 degrees is generated. The signals A and B are fed to bridge-connected transistors 2-5. To the input circuit of the T type FF circuit 11, a time constant circuit consisting of capacitors C1, C2 is connected. As a result, at the time of changing over the signals A and B, the signals A and B temporarily come to a level L, and the transistors 2-5 are turned conductive at the same time, and short circuit current can be prevented from flowing.
