The SN65LBC180 differential driver and Receiver
pair is a monolithic integrated circuit designed for bidirectional data Communication
over long cables that take on the characteristics of transmission lines. It is a balanced, or differential, voltage mode device that meets or exceeds the requirements of industry standards ANSI RS-485
and ISO 8482:1987(E). The device is 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.
