Overview
The SN65LBC174A16DWR is a quadruple RS-485 differential line driver produced by Texas Instruments. This device is designed for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 applications. It features four differential line drivers with 3-state outputs, making it suitable for balanced multipoint bus transmission. The SN65LBC174A is optimized for high-speed data transfer rates up to 30 million bits per second and is ideal for use in noisy environments due to its current limiting and thermal-shutdown circuitry.
