The SN65LBC175AD is a Quadruple RS-485 Differential Line Receiver, optimized for balanced multipoint bus communication at data rates up to and exceeding 50Mbps. The transmission media may be twisted-pair cables, printed-circuit board traces or backplanes. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment. Each receiver operates over a wide range of positive and negative common-mode input voltages and features ESD protection to 6kV, making it suitable for high-speed multipoint data transmission applications in harsh environments. This device is designed using LinBiCMOS, facilitating low power consumption and inherent robustness. Two EN inputs provide pair-wise enable control or these can be tied together externally to enable all four drivers with the same signal.
