description  
The SN55LBC172 is a monolithic quadruple  
differential line driver with 3-state outputs. This  
deviceisdesignedtomeettherequirementsofthe  
Electronics Industry Association (EIA) standard  
RS-485. The SN55LBC172 is optimized for  
balanced multipoint bus transmission at data  
rates up to and exceeding 10 million bits per  
second. The driver features wide positive and  
negative common-mode output voltage ranges,  
current limiting, and thermal-shutdown circuitry,  
making it suitable for party-line applications in  
noisy environments. The device is designed using  
the LinBiCMOS process, facilitating ultralow  
power consumption and inherent robustness.

The SN55LBC172 provides positive- and negative-current limiting and thermal shutdown for protection from  
line fault conditions on the transmission bus line. This device offers optimum performance when used with the  
SN55LBC173M quadruple line receiver. The SN55LBC172 is available in the 16-pin CDIP package (J), the  
16-pin CPAK package (W), or the 20-pin LCCC package (FK).  
The SN55LBC172 is characterized for operation over a military temperature range of –55°C to 125°C.
