The SN65LBC175A and SN75LBC175A are quadruple differential line receivers with 3-state outputs, designed for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 (Euro RS-485) applications.

These devices are optimized for balanced multipoint bus communication at data rates up to and exceeding 50 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.

Each receiver operates over a wide range of positive and negative common-mode input voltages, and features ESD protection to 6 kV, making it suitable for high-speed multipoint data transmission applications in harsh environments. These devices are 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.

The SN75LBC175A is characterized for operation over the temperature range of 0°C to 70°C. The SN65LBC175A is characterized over the temperature range from −40°C to 85°C.
