Hi,
I am facing problem always while i am making any circuit related to CMOS-IC 4000 series,that if i switch ON/OFF mains power supply 230VAC suddenly IC tooks spike & gives result that should come by any logic means example : Alarm gets ON,relay operated by IC gets ON etc.
I am looking for interface OR filter circuit which i can built at input pins of IC OR filter circuit which will avoid this malfunctioning of IC caused by spike /frequent ON-OFF in power.
Please suggest.
