Toggle flip-flops are ideal for building ripple counters as it toggles from one state to the next, (HIGH to LOW or LOW to HIGH) at every clock cycle so simple frequency divider and ripple counter circuits can easily be constructed using standard T-type flip-flop circuits. Since there are only two states, a T-type flip-flop is ideal for use in frequency division and binary counter design.īinary ripple counters can be built using “Toggle” or “T-type flip-flops” by connecting the output of one to the clock input of the next. A “Toggle flip-flop” gets its name from the fact that the flip-flop has the ability to toggle or switch between its two different states, the “toggle state” and the “memory state”.
