ABSTRACT:
An integrated circuit includes functional circuitry for performing normal operating functions of the integrated circuit, an output terminal which is accessible externally of the integrated circuit, and an output drive circuit (OB,OA) for receiving an output signal from the functional circuitry and driving the output signal to the output terminal. A switch (TG1,S1) is provided for selectively isolating the output terminal from the functional circuitry, and the switch is connected between the functional circuitry and the output drive circuit.
