Abstract
A scan output flip-flop is provided. The scan output flip-flop outputs a scan-out signal at a first output terminal and includes a selection circuit, a control circuit, and a scan-out stage circuit. The selection circuit is controlled by a first test enable signal to transmit a data signal on a first input terminal or a test signal on a second input terminal to an output terminal of the selection circuit to serve as an input signal. The control circuit is coupled to the output terminal of the selection circuit and controlled by a first clock signal to generate a first control signal and a second control signal according to the input signal. The second control signal is the inverse of the first control signal. The scan-out stage circuit is controlled by the first control signal and the second control signal to generate the scan-out signal.
