PURPOSE:To obtain a timing signal automatically at a desired time point by obtaining an OR between N pieces of signals and their complementary signals and then obtaining and outputting an AND of those signals. CONSTITUTION:The logical states of input signals A and -A are fixed when the signal A or -A is set at logic 1. Then a logical circuit 40 is switched. In the same way, it is decided by switching actions of logical circuits 41 and 42 that the logical states of input signals B and -B and input signals C and -C are fixed respectively. Then it can be decided that the logical states of signals A and -A as well as B and -B are fixed from a fact that a logical circuit 43 is switched to a voltage state. |
