Abstract
An output buffer circuit includes: a first transistor supplying a first power supply voltage to a first node upon turning on in response to an input signal; a second transistor supplying a second power supply voltage to a second node upon turning on in response to the input signal; a third transistor connecting between the first and second nodes upon turning on in response to a reverse phase signal of a signal on the first node; a fourth transistor connecting between the first and second nodes upon turning on in response to a reverse phase signal of a signal on the second node; a fifth transistor supplying the first power supply voltage upon turning on in response to the signal on the first node; and a sixth transistor supplying the second power supply voltage upon turning on in response to the signal on the second node.
