SN65LBC179DR Datasheet PDF - TI

description

●The SN65LBC179, SN65LBC179Q, and SN75LBC179 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). Both 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.
