Integrated circuit with two operating states |
摘要 |
A two-operating state integrated circuit includes a functional device that can selectively occupy a first mode or a second mode, e.g., standby mode and active mode. A separate, small-dimensioned contact pad serves for input of a control signal. A control device is provided for receiving the control signal and for switching the functional device between the first and second modes. In the presence of an active control signal, circuitry generates a state combination of several different control signals that cause a switchover from the first mode to the second mode. In the absence of the control signal the circuitry is transparent. The invention provides improved visual inspection without significant additional outlay for test instruments during a test.
