说明

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.

The SN65LBC180 combines a differential line driver and receiver with 3-state outputs and operates from a single 5-V supply. The driver and receiver have active-high and active-low enables, respectively, which can be externally connected to function as a direction control.
