摘要：
An output buffer is provided with a terminal, a first driver, a second driver and enable circuitry. The first driver is for driving the terminal to a voltage corresponding to a logic value of the output signal. The second driver is for driving the terminal to the same voltage as the first driver, when the output signal transitions in logic value. The enable circuitry responds to a transition in logic value of the output signal by, after a predetermined delay, enabling the second driver to drive the terminal. However, the enable circuitry only enables the second driver to drive the terminal for a predetermined time period.
