  • Output buffer circuits for reducing ground bounce noise
    Patent number: 4777389
    Abstract: An output buffer includes a pull-up transistor (N1), a first pull-down transistor (N3), a second pull-down transistor (N8), and a logic circuit (15). The logic circuit (15) is responsive to a data input signal making a high-to-low transition and the output signal making a high-to-low transition for maintaining the second pull-down transistor (N8) turned-off until after an output node has made the high-to-low transition, thereby reducing significantly the ground bounce noise.
