ABSTRACT:
An integrated circuit output driver provides high speed communication, such as between integrated circuits in spite of appreciable interconnection capacitance. The output driver reduces the current sourced or sunk from a circuit node during its switching as its voltage approaches power supply or ground voltages. This reduces the voltage swing and ringing at the circuit node during high speed communication, thus reducing switching time. The output driver provides full voltage swing under quiescent conditions, preserving minimum leakage currents in steady state.
