2 Description

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 the TI proprietary

LinBiCMOS™ with the low-power consumption of

CMOS and the precision and robustness of bipolar

transistors in the same circuit.
