Description

Quad EIA–485 Line Receiver

Specifications and features

The Motorola SN75175 is a monolithic quad differential line receiver with three–state outputs. It is designed specifically to meet the requirements of EIA–485, EIA–422A/23A Standards and CCITT recommendations. The device is optimized for balanced multipoint bus transmission at rates up to 10 megabits per second. It also features high input impedance, input hysteresis for increased noise immunity, and input sensitivity of ±200 mV over a common mode input voltage range of –12 V to 12 V. The SN75175 is designed for optimum performance when used with the SN75172 or SN75174 quad differential line drivers. It meets EIA Standards EIA–422A and EIA–423A, EIA–485 as well as CCITT Recommendations V.10, V.11, X.26, and X.27. The device is designed for multipoint transmission on long bus lines in noisy environments and has 3-state outputs. Its common-mode input voltage range is -12V to 12V with an input sensitivity of ±200 mV and input hysteresis of 50 mV typical. It has a high input impedance of 1 EIA-485 unit load and operates from a single 5.0V supply. The SN75175 is a plug-in replacement for MC3486 with lower power requirements.

Application Scenarios

The SN75175 is commonly used in electronic systems that require reliable communication over long bus lines in noisy environments. It can be used in industrial automation systems, building automation, communication networks, and other applications that utilize EIA–485 or EIA–422A/23A standards.
