The invention discloses an LVDS (Low Voltage Differential Signaling) receiving circuit with a wide common-mode input range. The LVDS receiving circuit comprises a common-mode conversion circuit, a main comparator circuit, a secondary comparison circuit and a logical judgment circuit, the common-mode conversion circuit is used for converting an external wide common-mode input differential signal into a signal with constant common-mode voltage and no attenuation of the differential signal; the main comparator circuit identifies the converted differential signal to complete differential-to-single-ended data conversion; the secondary comparator circuit is composed of two low-speed comparators; and the logic judgment circuit judges the output of the main comparator and the window comparator to ensure that the output of the input end of the circuit group is a constant level under the short circuit and disconnection conditions, so that the function of dynamic failure protection of the circuit is realized. The wide common-mode input circuit can realize discrimination of wide common-mode input signals ranging from-4V to 5V, and has a dynamic failure protection function.
