Abstract
An electrical circuit for testing primary internal signals of an ASIC. Only test pin is provided via which a selection can be made of a digital or analog signal to be observed. The electrical circuit includes a Schmitt trigger between the test pin and an output terminal of the electrical circuit. A test mode id activated when a switching threshold of the Schmitt trigger is exceeded. At least one sub-circuit is provided for the observation of a digital signal, having a resistor, an NMOS transistor, and an AND gate, at whose first input the digital signal is present. The resistor is between the test pin and the drain terminal of the NMOS transistor. The source terminal is connected to ground, and the gate terminal is connected to the output of the AND gate. The second input of the AND gate being connected to the output terminal of the electrical circuit.
