The SN55173, SN65173, and SN75173 are  
monolithic quadruple differential line receivers  
with 3-state outputs. They are designed to meet

the

TIA/EIA-423-B, TIA/EIA-485-A, and several ITU  
recommendations. The standards are for  
balanced multipoint bus transmission at rates up  
to 10 megabits per second. The four receivers  
share two OR enable inputs, one active when  
high, the other active when low. These devices  
feature high input impedance, input hysteresis for  
increased noise immunity, and input sensitivity of  
±200 mV over a common-mode input voltage  
range of 12 V to 12 V. Fail-safe design specifies  
thatiftheinputsareopencircuited, theoutputsare  
always high. The SN65173 and SN75173 are  
designed for optimum performance when used  
with the SN75172 or SN75174 quad differential  
line drivers.

THE SN55173 IS NOT RECOMMENDED  
FOR NEW DESIGNS.  
The SN55173 is characterized over the full military temperature range of 55°C to 125°C. The SN65173 is  
characterized for operation from –40°C to 85°C. The SN75173 is characterized for operation from 0°C to 70°C.
