ABSTRACT:
An output buffer circuit has a main driver including a first pMOS transistor and a first nMOS transistor for driving a load, and a second pMOS transistor and a second nMOS transistor for driving the load in coaction with the first pMOS transistor and the first nMOS transistor, and a predriver including a third pMOS transistor and a third nMOS transistor for driving the first pMOS transistor, a fourth pMOS transistor and a fourth nMOS transistor for driving the first nMOS transistor, a fifth nMOS transistor for driving the first pMOS transistor in coaction with the third nMOS transistor, and a fifth pMOS transistor for driving the first nMOS transistor in coaction with the fourth pMOS transistor.
