DESCRIPTION  
DE  
9
The SN55LBC180, SN65LBC180 and SN75LBC180  
differential driver and receiver pairs are monolithic  
integrated circuits designed for bidirectional data  
communication over long cables that take on the  
characteristics of transmission lines. They are  
balanced, or differential, voltage mode devices that  
meet or exceed the requirements of industry  
standards ANSI RS-485 and ISO 8482:1987(E).  
These devices are designed using TI's proprietary  
LinBiCMOS™ with the low-power consumption of  
CMOS and the precision and robustness of bipolar  
transistors in the same circuit.
