description  
The SN65LBC173A and SN75LBC173A are  
1A  
1B  
1Y  
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 LinBiCMOSt, facilitating low power consumption and  
robustness.  
The G and G inputs provide enable control logic for either positive- or negative-logic enabling all four drivers.  
When disabled or powered off, the receiver inputs present a high-impedance to the bus for reduced system  
loading.  
The SN75LBC173A is characterized for operation over the temperature range of 0°C to 70°C. The  
SN65LBC173A is characterized over the temperature range from –40°C to 85°C.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
