This device is designed using LinBiCMOS ,  
facilitating ultra-low power consumption and  
inherent robustness.  
NC – No internal connection  
The SN55LBC174 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  
SN55LBC173quadruple line receiver. The SN55LBC174 is available in the 16-pin CDIP package (J), the 16-pin  
CPAK (W), or the 20-pin LCCC package (FK).  
The SN55LBC174 is characterized for operation over the military temperature range of –55°C to 125°C.
