Abstract
In order to enable two different internal circuits to be controlled from one input pin of a C-MOS IC said pin is connected directly to an input of a first circuit and via the emitter-collector path of a transistor to the input of a second circuit. The base of this transistor is connected to one of the supply voltages, so that this transistor can conduct only when the voltage on said input pin is higher or lower than the positive or negative supply voltage respectively.
