ABSTRACT:
A buffer and organic light emitting display with data driving circuit using the buffer is provided. A buffer comprises a first capacitor for receiving an analog voltage; a first inverter having an input terminal connected to the first capacitor; a second inverter having an input terminal connected to an output terminal of the first inverter through a second capacitor; a third capacitor connected to an output terminal of the second inverter; a first transistor for controlling a current which flows from a first power source to a data line so that the buffer output voltage is supplied to the data line in response to a control signal supplied to the third transistor which is connected between the data line and the first capacitor.
