A decision feedback equalization (DFE) receiver and method are provided. The DFE receiver is configured to sample data bits from a data bus. The DFE receiver includes a data sampler configured to sample a current data bit from the data bus using one of a first, second and third voltage reference. The DFE receiver also includes multiplexing logic configured to select one of the first, second and third voltage references based on a prior data bus level. The wherein the first voltage reference is selected if the prior data bus level was a logic zero. The second voltage reference is selected if the prior data bus level was a logic one. The third voltage reference is selected if the prior data bus level was tri-state.
