ABSTRACT:
A synchronous counter comprises one D flip-flop circuit for performing divide-by-2 frequency division of a clock signal CK, JK flip-flop circuits for, when input signals have HIGH levels (logical value 1), inverting the levels of the output signals in synchronization with the clock signal CK, logic circuits for inputting control signals to the JK flip-flop circuits, lower-stage signal assembling circuits for grouping the output signals from the JK flip-flop circuits into two-signal-unit groups to produce logical product signals of the signals in these two,signal-unit groups, and upper-stage signal assembling circuits for further handling the output signals from the lower-stage signal assembling circuits, thereby firstly simultaneously satisfying an increase in speed of the counting operation as well as simplification of the wiring pattern and reduction in the circuit area and secondly realizing further increase in the counting operation.
