A = 1 and C = 0, there is a conflict and the output is unknown (X). ) If both the buffers are enabled, with A = 1 and C = 0, the combined output is Hi-Z (high impedance). O If one of the buffers is disabled, the combined output is the same as the other output. If one of the buffers is disabled, the combined output is Hi-Z (high impedance).
