An output driver circuit offers wave-shaping and logic level adjustment for high speed data communications in a synchronous memory such as a dynamic random access memory (DRAM). Level adjustment is obtained by resistive division between a termination resistor and controllable impedances between an output node and VDD and VSS power supplies. Wave-shaping functions include slew rate modification of the signal at the output node, by sequentially turning on or off output transistors in response to a transition in an input signal. Different schemes of weighting the output transistors obtains different wave-shaping characteristics of the output signal.
