A cell for an arithmetic logic unit includes a first input; a second input; a carry-in input; a first control input and a second control input; and a circuit connected to the first input, the second input, the carry-in input, the first control input, and the second control input. The circuit has a first output and a second output, the second output having a first value as a function of the first input and the second input when the first control input and the second control input are supplied values equal to a value at the carry-in input, and having a second value as a function of the first input and second input when the values at the first control input and the second control input are independent of the value at the carry-in input.

A logic gate comprises a first switch, a second switch, a data network and a keeping circuitry. The first switch is adapted to connect a logic node to a first potential responsive to a transition of an enabling signal. The second switch is adapted to connect the logic node to a second potential via an electrical path responsive to a transition of the enabling signal. The data network is serially connected within the electrical path. The keeping circuitry comprises third and fourth switches serially connected between the logic node and the first potential and being controllable separately from each other, the third switch being adapted to be closed in case a potential on the logic node assumes the first potential and to be opened in case the potential on the logic node assumes the second potential.

Some embodiments show a digital fault detection circuit with an input circuit comprising an input and at least one output, wherein a first signal state at the input causes a predetermined signal state at the output and a second signal state at the input leaves the output floating. Moreover the digital fault detection circuit may comprise a signal line with a signal line input and a signal line output, wherein the signal line input is coupled to the output of the input circuit and furthermore a keeper circuit coupled to the signal line output and configured to keep the signal line at the predetermined signal state, after the signal state at the input has changed from the first signal state to the second signal state. The digital fault detection circuit may further comprise at least one fault detector cell, which is coupled to the signal line between the signal line input and the signal line output and which is configured to change the state of the signal line which is otherwise kept by the keeper circuit, in response to a fault.

A transmission device has a device for generating a signal pair and a device for generating a recovered data signal. The device for generating the signal pair is formed to output a first data signal either as first signal or as first complementary signal in response to a value of a switching signal. The device for generating a recovered data signal is, in turn, formed to output the first signal as a first recovered data signal or the first complementary signal as the first recovered data signal in response to a value of the switching signal.
