SN75LBC174AN

翻两番RS- 485微分方程线路驱动器 QUADRUPLE RS- 485 DIFFERENTAIL LINE DRIVERS

DESCRIPON

The SN65LBC174A and SN75LBC174A are quadruple differential line drivers with 3-state outputs, designed for TIA/EIA-485 RS-485, TIA/EIA-422 RS-422, and ISO 8482 applications.

These devices are optimized for balanced multipoint bus transmission at signaling 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.
