Wired-AND logic is a technique used in digital circuits where multiple open-collector or open-drain outputs are connected to a common wire, creating a logical AND function without the need for additional gates. This approach is particularly useful in situations where multiple devices need to share a common bus line, allowing any device to pull the line low, thus achieving a collective AND operation across the connected outputs.
