Abstract
A buffer for a driving circuit includes a first transistor, a second transistor and a slew rate controlling circuit. The first transistor serves to provide a current to an output terminal. The second transistor serves to sink a current from the output terminal. The slew rate controlling circuit serves to control slew rate of at least one of the first transistor and the second transistor according to the input signal. The managing circuit serves to prevent the first transistor and the second transistor from turning on simultaneously.
