Abstract

A method is described that compares two voltages, one of the voltages indicative of a data line voltage, a second of the voltages indicative of a reference voltage. An input signal is sent to each of a plurality of drivers where at least one of the drivers is coupled to the data line. The input signal is based upon the comparison. A bias is applied to a transistor from the input signal, the bias keeping the transistor in a high output impedance state when the two voltages are the same.
