Not to be confused with can't happen.

Don't care or don't care condition is a digital signal state designation often represented by X that indicates the actual signal value or values have no impact on the outcome a circuit. Don't care values can be inputs that do not affect the output of a circuit or outputs that do not matter for a specific combination of inputs. Unlike can't happen conditions, don't care terms are still valid inputs however they do not influence the output value.
