A flip-flop for transmitting a scan input and data for scan-testing a semiconductor circuit is provided. The flip-flop includes a first pulse signal generator which generates a first pulse signal in response to a scan enable signal and an inversed scan input signal. A second pulse signal generator generates a second pulse signal in response to the scan enable signal and a scan input signal. A signal transmitter receives a data signal and transmits the data signal to a first node in response to either one of the first and second pulse signals. A signal latch unit receives the data signal transmitted to the first node, and latches and outputs the data signal in response to another one of the first and second pulse signals.
