A circuit arrangement may include a scan test input stage having a test input for receiving a test signal, wherein the scan test input stage can be switched in high-impedance state; a data input stage having a data input for receiving a data signal, wherein the data input stage can be switched in high-impedance state. The circuit arrangement may further include a latch coupled to at least one output of the scan test input stage and to at least one output of the data input stage; and a drive circuit, which is configured to generate a pulsed clock signal for the data input stage and a signal for driving the scan test input stage.
