description
●The SN65LBC172A and SN75LBC172A are quadruple differential line drivers with 3-state outputs, designed or TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 applications.
●These devices are optimized for balanced multipoint bus transmission at signalling rates up to 30 million bits per second. The transmission media may be printed-circuit board traces, backplanes, or cables. 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 driver features current limiting and thermal-shutdown circuitry making it suitable for high-speed mulitpoint data transmission applications in noisy environments. These devices are designed using LinBiCMOS, facilitating low power consumption and robustness.
