Abstract: An output driver for providing bus signals at a driver output in response to an input signal, the driver having a driver input signal responsive to the input signal, a supply voltage terminal and a ground terminal. The driver includes an improved clamping of an initially ON (i.e. high going) output pulse of the driver and adds an active pull-up function inside the integrated circuit that does not change the external circuit nor require additional functional external circuit connections.
