A data driver and an organic light emitting display device using the same, in which power consumption and a layout area thereof are reduced. The data driver includes: a shift registering part adapted to supply sampling signals; a sampling latching part including sampling latches adapted to store data in response to the sampling signals; and a holding latching part including holding latches adapted to receive the data stored in the sampling latches in response to an externally supplied source output enable signal. Each of the sampling latches includes sampling bit storages. Each of the sampling bit storages includes: a first input unit adapted to receive a certain bit of the data; a first capacitor adapted to store voltage corresponding to a logic signal of the certain bit supplied from the first input unit; and a first inverter adapted to inverse the logic signal stored in the first capacitor.
