Overview
The SN75174N, manufactured by Texas Instruments, is a monolithic quadruple differential line driver with 3-state outputs. It is designed to meet the requirements of ANSI standards EIA/TIA-422-B and RS-485, as well as ITU recommendation V.11. This component is optimized for balanced multipoint bus transmission at rates up to 4 megabits per second. It is particularly suited for noisy environments, offering a wide common-mode output voltage range and features such as thermal shutdown protection and current limiting. The SN75174N operates from a single 5V supply and is functionally interchangeable with the MC3487. It is widely used in industrial, telecommunications, and networking applications where reliable data transmission is critical.
