Hello guys I need some help with a circuit I'm building. http://www.sentex.ca/~mec1995/circ/relay62.html I build it and it work for a few mins and then the chip gets hot and it dies. I have built it 4 times and it does it every time I'm using a 12v power supply and using it to switch a transistor. I'm using a cd4001ube chip any help would be great I need this for my big project It's really making me mad. Thanks all.
