PURPOSE:To decrease the number of additional auxiliary latched down to a half, by setting an auxiliary latch with every 2nd system latch and connecting the auxiliary latch to every 2nd system latch to form the channels of two types of shift registers. CONSTITUTION:The inputs and outputs are connected to each other among system latches L1-L8 to form a shift register channel. In addition to this 1st shift register channel, the 2nd shift register channel of L1-T1-L3-T2-L5-T3-L7 is formed with auxiliary latches T1, T2 and T3. When a gate signal G1 is actuated, the 1st shift register channel of L1-L2-L3-L4-L5-L6-L7-L8 is actuated. Then a gate G2 is actuated, and as a result the 2nd shift register channel can be actuated. |
