I have a device that takes an input from a motor vehicle - the signal is a 12v pulse. I feed this directly into a 4081 IC. In the vast majority of cases I never have a problem, but occasionaly I do. Do you think the 12v is too aggressive ? (it may peek at 14 v) - The IC specs do say they operate up to 18v so it is within the specs.
Could someone help me with a design suggestion to protect the front end in the case of a 'spike' ? would a zener help and if so, how could it be connected ? Any help would be greatly appreciated...
