Overview
The SN65LBC172ADWR, produced by Texas Instruments, is a quadruple differential line driver designed to meet the requirements of TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 applications. This device is optimized for balanced multipoint bus transmission at high signaling rates, making it suitable for noisy environments and long bus lines. It features ultra-low power consumption and robustness, thanks to its LinBiCMOS technology. The SN65LBC172ADWR is available in various packages, including the 20-pin wide-body small-outline inline-circuit (SOIC) package, and is characterized over an industrial temperature range of −40°C to 85°C.
