Claim 5:
6. The integrated circuit as claimed in claim 1, wherein the scan flip-flops comprise data output connections and wherein each ring oscillator circuit is assigned a scan flip-flop group with a plurality of the multiplicity of scan flip-flops whose data output connections are connected to a control input connection of the input multiplexer of the chain of the ring oscillator circuit such that when the plurality of the multiplicity of scan flip-flops store a predefined bit combination, the plurality of the multiplicity of scan flip-flops switch the input multiplexer such that the input multiplexer outputs the output bit fed back via the feedback line to the first logic gate of the chain, wherein the integrated circuit comprises a combination logic circuit via which the data output connections of the plurality of the multiplicity of scan flip-flops are connected to the control input connection of the input multiplexer.
