What should be the recommended protection circuit for line receiver pins?

I'm using a balanced connection.

    Hi Suzuki-san,

    For SRC4392 input reciever goes, transformer coupling is commonly employed to provide isolation and to improve common-mode noise rejection. 0.1μF capacitors are utilized for AC-coupling the transformer to the line receiver inputs.

    Best regards,
