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.
