Systems and methods for providing differential line drivers include a device having an input configured to receive an input signal and a driver circuit configured to generate a first output and a second output from the input signal. The second output is a complementary output to the first output, wherein the first output has a first transfer characteristic and the second output has a second transfer characteristic different than the first transfer characteristic. The first and second transfer characteristics include an offset from respective input values of the input signal. The device further includes an output configured to output as a differential signal the first output and the second output generated by the driver circuit, wherein the offset in the first and second transfer characteristics defines a fail-safe output state for the differential signal.
