Patent abstract
A circuit arrangement having complementary data lines of a dual rail data bus, wherein in a regular operating phase the complementary data lines carry complementary signals, and in a precharge phase the complementary data lines assume an identical logic state or the same electrical potential. The circuit arrangement also has a device for detecting manipulation attempts, the device having a detector circuit, which outputs an alarm signal upon the occurrence of an identical logic state on both data lines in the regular operating phase.
