PURPOSE:To increase the operating margin, by connecting MOS transistors (TRs) for discharge in series with outputs of each stage and switching the TRs with a transmission pulse in the same stage. CONSTITUTION:Clock pulses phi1, phi2 in two-phase are applied to lines 6, 7. An input pulse is applied to a line 9. TRs QT1, QT2 are MOS TRs for transmission transmitting an output of the pre-stage with a delay, a TRQC is a MOS TR for discharge outputting a scanning pulse, and the TRQD is a discharge MOS TR for discharging a level stored at output terminals O1-O3 of each stage. The TRQD is switched with a polarity inversion circuit 11 comprising TRs Ql and Qd. |
