摘要:
A data processing system having an improved output circuit which can set its output terminal optionally at a high impedance state and at a voltage clamped state in a standby mode. The system includes an output circuit capable of setting the output terminal at the high impedance state and the voltage clamped state in response to a first control signal and a second control signal, respectively.
