The SN75ALS172A comprises four line drivers  
with 3-state differential outputs. They are  
designed to meet the requirements of ANSI  
Standards EIA/TIA-422-B and RS-485 and ITU  
Recommendation V.11. This device is optimized  
for balanced multipoint bus transmission at rates  
of up to 20 Mbaud. Each driver features wide  
positive and negative common-mode output  
voltage ranges, making it suitable for party-line  
applications in noisy environments.

NC – No internal connection  
The SN75ALS172A provides positive- and negative-current limiting and thermal shutdown for protection from  
line-fault conditions on the transmission bus line. Shutdown occurs at a junction temperature of  
approximately 150°C.  
The SN75ALS172A is characterized for operation from 0°C to 70°C.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
