One of the most commonly used clocking systems has two latches, a master latch (MASTER LT) and a slave latch (SLAVE LT) for one unit of storage (Fig. 1). For the shift function, the latches are separately driven by shift clock A and shift clock B, whereas for normal operation, they are driven by clocks A and B. All clocks are non overlapping pulse trains, as shown in Fig. 2. Such a design is generally free from hazards.
