Abstract
Abstract An integrated semiconductor circuit configuration includes one input of the circuit configuration for receiving a ternary input signal, and two outputs of the circuit configuration for supplying two binary output signals converted from the input signal. First, second, third and fourth resistors are connected in series between an operating voltage potential and a reference potential, defining a first connecting node between the first and the second resistors, a second connecting node between the second and the third resistors, and a third connecting node between the third and the fourth resistors. The second connecting node forms the input of the circuit configuration. A first threshold value decision circuit has an input connected to the first connecting node and has an output. A second threshold value decision circuit has an input connected to the third connecting node and has an output. A logic circuit is connected to the outputs of the threshold value decision circuits and has outputs forming the outputs of the circuit configuration.
