Abstract
Integrated digital semiconductor circuit, including a plurality of inputs, a common constant-current source for selectively supplying the inputs, the inputs being operable in a '1' logic level state and a '0' logic level state, internal switching means for switching the inputs to a first operating state of the common constant-current source in which all of the inputs are at the '0' level and to a second operating state of the common constant-current source in which a given number of the inputs are at the '1' level and the other of the inputs are at the '0' level, a resistor being connected between the common constant-current source and each of the inputs, each of the resistors being identical to each other and being constructed in dependence on the first and second operating states of the common constant-current source.
