Overview
The SN65LBC172ADWRG4, produced by Texas Instruments, is a quadruple differential line driver designed for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 applications. These devices feature 3-state outputs and are optimized for balanced multipoint bus transmission at high signaling rates. The SN65LBC172A and SN75LBC172A are part of the same family, with the SN65LBC172A operating over a temperature range of –40°C to 85°C and the SN75LBC172A operating from 0°C to 70°C. They are built using LinBiCMOS technology, which ensures low power consumption and robust performance.
