Patent ID: 7372291

Claim:
A slew rate control circuit, comprising: a receiver capable of receiving input signals; an output generator capable of generating output signals based on the input signals; an electrical interconnection coupling an output of the receiver and an input of the output generator; and a voltage clamp capable of clamping a voltage on the electrical interconnection between a first known voltage reference level and a second known voltage reference level, the voltage clamp comprising, a driver circuit coupled to the electrical interconnection, the driver circuit capable of preventing the voltage on the electrical interconnection from rising above the first known voltage reference level and from falling below the second known voltage reference level, a first current source coupled to the driver circuit, the first current source capable of outputting driving current to the driver circuit to prevent the voltage on the electrical interconnection from falling below the second known voltage reference level, and, a second current source coupled to the driver circuit, the second current source capable of sinking current from the driver circuit to prevent the voltage on the electrical interconnection from rising above the first known voltage reference level.
