Abstract

Circuit arrangement having complementary data input nodes for reception of a dual rail data signal and complementary data output nodes for outputting a dual rail data signal. A connection switch is connected to complementary data nodes by means of which the complementary data nodes can be connected to one another with a low resistance, a control unit is provided for generating a first control signal for the connection switch, and the circuit arrangement is designed to be operated in two operating modes, in which case in a power saving mode, the connection switch is switched by the control unit to have a high resistance, and in a security node, the connection switch is switched by the control unit to have a low resistance when the potential at the complementary data nodes is intended to be equalized.
