The SN65LBC174 and SN75LBC174 are  
monolithic, quadruple, differential line drivers with  
3-state outputs. Both devices are designed to  
meet the requirements of the Electronics Industry  
Association Standard EIA-485. These devices  
are optimized for balanced multipoint bus  
transmission at data rates up to and exceeding  
10 million bits per second. Each driver features  
wide positive and negative common-mode output  
voltage ranges, current limiting, and thermal-  
shutdown protection, making it suitable for  
party-line applications in noisy environments.  
Both devices are designed using LinBiCMOS ,  
facilitating ultra-low power consumption and  
inherent robustness.

BoththeSN65LBC174andSN75LBC174provide  
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 SN65LBC174 and  
SN75LBC174 are available in the 16-terminal DIP  
package (N) and the 20-terminal wide-body small  
outline intergrated circuit (SOIC) package (DW).
