Introduction

AI Translation

The SN55LBC180, SN65LBC180, and SN75LBC180 differential driver and receiver pairs are monolithic integrated circuits designed for bidirectional data communication over long cables with transmission line characteristics. They are balanced or differential voltage mode devices that meet or exceed the requirements of the industry standards ANSI RS - 485 and ISO 8482:1987(E). These devices are designed using proprietary LinBiCMOS, offering the low power consumption of CMOS along with the precision and robustness of bipolar transistors in the same circuit.

The SN55LBC180, SN65LBC180, and SN75LBC180 combine a differential line driver and a receiver with three - state outputs and are powered by a single 5V supply. The driver and receiver have active - high and active - low enable terminals, respectively, which can be externally connected together for direction control. The driver differential outputs and receiver differential inputs are connected to separate terminals for full - duplex operation and are designed to present a minimum load to the bus, whether disabled or powered down (VCC = 0).

These devices have a wide common - mode voltage range, making them suitable for point - to - point or multi - point data bus applications. They also provide positive and negative output current limiting and thermal shutdown features to avoid line fault conditions. The line driver shuts down at a junction temperature of approximately 172°C.

The SN75LBC180 operates over the commercial temperature range of 0°C to 70°C. The SN65LBC180 operates over the industrial temperature range of – 40°C to 85°C. The SN55LBC180 has a temperature range of – 55°C to 125°C.
