Abstract

PURPOSE:To generate a reset signal surely, by respectively setting the output point of each inverter at an odd number stage among inverters to the circuit power supply voltage, and that of an even number of stage to the reference potential. CONSTITUTION:Inverters 42-45 in cascade connection are provided between the output A of a time constant circuit 41 and a reset terminal -R of an external circuit 1. Capacitors C2 and C3 are respectively connected between outputs B, D of odd step inverters 42, 44 and the output line of a circuit power supply 2, and the output, B, D are pulled up to the power supply voltage for a given period after the application of power supply. Capacitors C4, C5 are respectively connected between outputs C, E of the even step inverters 43, 45 and ground being the reference voltage to pull down the outputs C, E to ground for a given period after the application of power supply.
