ABSTRACT:
A shift register comprises a plurality of latch circuits for latching time series signals inputted thereto, a multiplexer for selecting outputs of the latch circuits in sequence, and a clock control circuit for generating clocks used for controlling selection timings of the multiplexer, wherein the timing for selecting the output of a certain latch circuit is delayed with respect to the latch timing of the certain latch circuit by a predetermined timing. Accordingly, the number of elements constituting the shift register circuit is decreased and the power consumption is reduced.
