Abstract

A method is for driving an output buffer for outputting a datum of a certain voltage level with a certain slew-rate as a function of an input datum and a first enabling signal. The first enabling signal commands the buffer to a normal functioning state or to a high impedance state. The output buffer has an output stage controlled at least by a pull-up driving circuit and a pull-down driving circuit, and an enabling circuit input with the input datum and a second enabling signal and generating control signals. The control signals may be in phase or in phase opposition depending on whether the second enabling signal is active or disabled, and they are input into the respective driving circuits.
