The SN65LBC172 and SN75LBC172 are  
monolithic quadruple differential line drivers with  
3-state outputs. Both devices are designed to  
meet the requirements of EIA Standard RS-485.  
These devices are optimized for balanced  
multipointbustransmissionatdataratesuptoand  
exceeding 10 million bits per second. Each 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.  
Both devices are designed using LinBiCMOS ,  
facilitating ultra-low power consumption and  
inherent robustness.

BoththeSN65LBC172andSN75LBC172provide  
positive- and negative-current limiting and  
thermal shutdown for protection from line fault  
conditions on the transmission bus line. These  
devices offer optimum performance when  
used with the SN75LBC173 or SN75LBC175  
quadruple line receivers. The SN65LBC172 and  
SN75LBC172 are available in the 16-pin DIP  
package (N) and the 20-pin wide-body small-  
outline inline-circuit (SOIC) package (DW).

The SN75LBC172 is characterized for operation  
over the commercial temperature range of 0°C to  
70°C. The SN65LBC172 is characterized over the  
industrial temperature range of –40°C to 85°C.
