Abstract: PURPOSE:To decrease the number of MOS transistors constituting 1 stage each, by forming each stage by use of a switching MOS transtor responding to a storage element of a prescribed time constant, and a one-way conducting MOS transistor. CONSTITUTION:When an MOS transistor T1 conducts by a prescribed clock phi2, voltage of a joint 1 rises through a capacitor forming a storage circuit of a prescribed time constant, by a high level input from a terminal 11.

Accordingly, each stage of a shift register  is formed by a few MOS transistors, for instance, 2 groups, etc. In this way, it is possible to obtain a shift register of high density, high speed and low power  consumption.
