Patent ID: 7747790

Claim:
An integrated driver circuit for a Local Interconnect Network LIN bus, the circuit comprising: a first input terminal at which an input data signal is applied; an output terminal, which is connected to a bus line of the LIN bus and at which an output data signal dependent on the input data signal is outputted; at least one second input terminal, whereby the input data signal is applied either at the first input terminal or the second input terminal; a transmit circuit, which is looped between the output terminal and the first and second input terminal and which generates the output data signal from the input data signal, whereby the transmit circuit, depending on a specification selection signal, generates the output data signal according to a first LIN bus specification or according to at least one second LIN bus specification, wherein the first LIN bus specification is different than the second LIN bus specification; and a specification selection circuit, which is coupled to the first and second input terminal and the transmit circuit and generates the specification selection signal depending on whether the input data signal is applied at the first input terminal or the at least second input terminal.
