PURPOSE:To obtain a shift register which is small in size and power consumption and operable by two-phase drive by separately using two-phase clocks as the driving pulses of each driving switch in adjacent unit bit circuits and, at the same time, the output pulse of the succeeding-stage driving switch as the resetting pulse of the preceding-stage resetting switch. CONSTITUTION:Two-phase clocks are separately used as the driving pulses phim of each driving switch Q1k and Q1k+1 in two adjacent unit bit circuits 2k and 2k+1. Then the output pulse phick+1 of the driving switch Q1k+1 in the succeeding-stage unit bit circuit 2k+1 is used as the resetting pulse of a resetting switch Q3k+1 in the preceding-stage unit bit circuit 2k. Therefore, impression of resetting pulse from the outside is not required, but supply of driving pulses for directly driving loads to the unit bit circuits. |
