A slew rate control circuit includes a receiver for receiving input
signals and an output generator for generating output signals based on
the input signals. The slew rate control circuit also includes an
electrical interconnection coupling an output of the receiver and an
input of the output generator. In addition, the slew rate control circuit
includes a voltage clamp for clamping a voltage on the electrical
interconnection between two known voltage reference levels. The voltage
clamp may include a first current source for providing driving capacity
to a driver circuit to prevent the voltage on the electrical
interconnection from falling below one known voltage reference level. The
voltage clamp may also include a second current source and a third
current source for providing sinking capacity to the driver circuit to
prevent the voltage on the electrical interconnection from rising above
the other known voltage reference level.
