Abstract

PURPOSE:To avoid the change in the circuit even with the increase/decrease in the number of digits for the coincidence circuit of the time sharing type counter, by giving a clock signal to the 1st latch circuit and giving the set signal to the 1st and 2nd lach circuits. CONSTITUTION:While the set signal S is at H level, the content counted at the counters A, B are outputted to a comparator C every digit sequentially with the signal fed to number of digit set terminals K0-K3. The comparator C compares the content of the counters A, B each digit, and if in coincidence, the signal of H level is outputted to an AND circuit AND and if in uncoincidence, the signal of L level, and it is applied to the data input terminal D of a latch M1. Clock signals D0-D3 are applied to a storbe terminal of the latch M1, the output of the latch M1 is applied to the data input terminal of the latch M2, and the set pignal is applied to the strobe terminal.
