Title: Ring counter circuit
Inventor: ISHIDO TEIICHI
IPC: H03K23/54
Filed: 1984-05-14
Abstract: PURPOSE:To avoid increasing circuit components regardless of increased output bit number by forming the titled counter circuit with a D flip-flop with one set/ reset and shift registers of a number corresponding to the output bit number. CONSTITUTION:The DF (D flip-flop) 40 and all SFT 21, 22,-2m are reset by a reset signal and output bits Q0-Qn-1 are all zero. A Q output 100 in this case goes to the initial state of logical 1. Since the Q output 100 is latched to the SFT21 at the leading of an input clock signal inputted to a terminal CP of the SFT21 after the release of reset, the Q0 output 101 goes to logical 1. Since the Q0 output 101 is inverted by an inverter circuit 3 and sets the DF40, the Q output 100 goes to ''0''. When one pulse is generated in the final output bit Qn-1, the DF40 latches a D terminal input 0 (common) at the leading of the Q7 output 102 of the SFT2m, the Q output 100 goes to logical 1 and the system restores to the initial state.
