ABSTRACT:
Disclosed is an output buffer circuit having low noise characteristics, comprising a control section for detecting whether a driving voltage of more than a normal voltage is applied or not, and generating a control signal on the basis of detection result thereof; and a pull-up section for enabling a voltage down to be selectively caused between a driving voltage supplying terminal and an output terminal of said buffer circuit in response to said control signal. By the output buffer, it is possible to considerably reduce a ground bounce noise occurring upon a driving voltage of more than a normal voltage being applied. Thus, the total ground level of a semiconductor device, in which the output buffer is embodied, can be stabilized, and therefore stability of the device can be enhanced.
