Product Summary

The SN65LBC179DR 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. The SN65LBC179DR is balanced, or differential, voltage mode devices that meet or exceed the requirements of industry standards ANSI RS-485 and ISO 8482:1987(E) . The SN65LBC179DR combines a differential line driver and differential line receiver and operate from a single 5-V supply.
