A data coupler includes first and second acoustic isolation transformers that develop first and second isolated output signals in response to first and second modulated input signals. A first and a second transmitter is coupled to the first and second acoustic isolation transformers to receive a first and a second data input signal and generate the first and second modulated input signal in response to the first and second data input signals. A first and a second receiver is coupled to the first and second acoustic isolation transformers to receive the first and a second isolated output signals and generate first and second demodulated signals responsive to the first and second isolated output signals. An output decision circuit is coupled to the first and second receivers to receive the first and second data output signals and generates a data output signal responsive to the first and second demodulated signals.
