ABSTRACT:
An output buffer includes an NAND circuit, a first N channel MOS transistor connected between a power supply node and an output node, a second N channel MOS transistor connected between the output node and a ground node, the first to third drive circuits, and a delay circuit. The power supply voltage is first supplied to the gate of the second N channel MOS transistor by the second drive circuit. After a delay time delayed by the delay circuit has passed, boosted voltage is supplied to the gate of the second N channel MOS transistor by the third drive circuit. Accordingly, the output buffer is not influenced by the ringing and the pull-down characteristic improves.
