Overview
The SN65LBC172A16DWR is a quadruple differential line driver produced by Texas Instruments. It is designed for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 applications. This device is optimized for balanced multipoint bus transmission at signaling rates up to 30 million bits per second. The SN65LBC172A is characterized for operation over a temperature range of –40°C to 85°C, making it suitable for a wide range of environments. It features 3-state outputs and is built using LinBiCMOS technology, which facilitates low power consumption and robustness.
