MASTER-SLAVE FLIP-FLOP, TRIGGER FLIP-FLOP AND COUNTER

摘要

A master latch (1) is constituted of a static circuit and a slave latch (2) is constituted of a dynamic circuit. As compared with the case where the slave latch is constituted of a static circuit, the number of circuit elements is decreased and reduction in size and area of a master-slave flip-flop is realized. Since the master latch is constituted of a static circuit, data can be held stably at the time of waiting when the master latch is set in a data holding state at the time of waiting.
