Why does my integrated circuit explode with the error: “The pin voltage was taken above the positive supply voltage…”?
A. This warning message is presented when the voltage on an individual pin of an integrated circuit (IC) is higher than the positive supply voltage by more than the rated value (normally 1V). This will occur when you use a higher voltage (such as 9V) in your circuit without changing the supply voltage (such as with a power connector) from the default 5V supply. To solve this problem, use a power connector to make sure the supply voltage for your IC is higher than or equal to the voltage applied on any individual pin. In most cases, connect the power connector in parallel with the battery or voltage source you are using to drive your input if this would also be connected to your IC.
