5.4.1 Overview

The SN65LBC174A-EP is a quadruple differential line driver with tri-state outputs, designed for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 (Euro RS-485) applications. This device is optimized for balanced multipoint bus communication at data rates up to and exceeding 30 million bits per second. 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. The transmitter features ESD protection to 12 kV on driver outputs, making it suitable for high-speed multipoint data transmission applications in harsh environments. These devices are designed using LinBiCMOS, facilitating low-power consumption and 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.
