PCT No. PCT/DE92/00131 Sec. 371 Date Sep. 16, 1993 Sec. 102(e) Date Sep. 16, 1993 PCT Filed Feb. 22, 1992 PCT Pub. No. WO92/17016 PCT Pub. Date Oct. 1, 1992A receiving comparator for a data-transmission system comprising at least one control unit and data-transmission lines, in particular for at least one Controller Area Network (CAN) controller and one CAN bus system having a CAN bus (CB) is proposed, which is distinguished by the feature that the individual circuit elements are monolithically integrated. By generating a switching threshold which is independent of the operating voltage and temperature with the aid of a current source (IS), one prevents the CAN bus potentials from being asymmetrically influenced. The arrangement guarantees a processing of digital signals with a high data rate, whereby the input common-mode range extends up to above the supply voltage and to below ground.
