ABSTRACT:
An output buffer circuit includes a first output buffer section and a second output buffer section. The first output buffer section includes complementary semiconductors. The second output buffer section includes complementary semiconductors and is connected in parallel with the first output buffer section. The second output buffer section starts to output an second output signal after an output voltage of the output buffer circuit reaches a reference voltage indicative of one of an on-state and an off-state by a first output signal of the first output buffer section.
