Output driver capable of controlling a short circuit current

摘要

An output driver capable of controlling a short circuit current includes a driving unit and a driving control unit. The driving unit receives a first driving signal and a second driving signal in response to a control signal and generates an output signal. The driving unit control unit includes a driving unit copying unit having the same construction as the driving unit and compares an output copying signal generated from the first and second driving signals by the driving unit copying unit with a reference voltage and generates the control signal that controls delays of the first and second driving signals in a test mode.
