In a bridge adder circuit, a first and a second complementary pair of current mirrors is connected between the input terminals and a positive and a negative supply voltage bus, respectively, to control a first and a second push-pull output stage. The outputs of the push-pull output stages are connected to the respective inputs through first resistors and to a common output node through second resistors. As a result, a universal circuit element for a multivalued logic element, such as ternary logic or 5-valued logic is provided.
