PURPOSE:To constitute the titled circuit with lease circuit elements by constituting the titled circuit with a signal selection circuit and an output holding circuit instead of a shift register to hold a parallel data. CONSTITUTION:The titled circuit comprises a latch circuit 1 to hold parallel data by a latch pulse 6, a signal selection circuit 2 to sequentially select parallel data held preliminarily in a counter initialized by a reset signal 13 by using a selection signal generated by supporting clock pulses 13 equal to the parallel data in number, and an output holding circuit 3 to hold a one-bit data selected by the signal selection circuit 2 at every clock pulse 12 which is initialized by the reset signal 13. As a result, the titled circuit can be constituted with less number of circuit elements. |
