ABSTRACT:
An object of the present invention is to provide a circuit device in which the power consumption can be reduced without the dedicated signal. A circuit device (1) comprising a D flip-flop (F0) for receiving a pulse of a clock signal (CK) to introduce data thereinto and output said introduced data and a shift register (2), comprising the D flip-flops (F1to F7) for introducing the data thereinto in accordance with the pulse to output the introduced data, for processing the outputted data from the D flip-flop (F0), wherein the circuit device (1) comprises a control circuit (3) for controlling whether the D flip-flops (F1to F7) are supplied with the pulse of the clock signal (CK) on the basis of outputted data from the D flip-flop (F0) in accordance with the pulse of the clock signal (CK) and data to be introduced into the D flip-flop (F0) in accordance with the next pulse.
