TI SN75LBC174DWR

The SN65LBC174 and SN75LBC174 are monolithic quadruple differential line receivers with three-state outputs. Both devices meet the requirements of Electronic Industries Association standard EIA-485. These devices are optimized for balanced multipoint bus transmission at rates up to and exceeding 10 Mbit/s. Each driver features a wide positive and negative common-mode output voltage range, current limiting, and thermal shutdown protection, making them suitable for party-line applications in noisy environments. Both devices are designed using LinBiCMOS™ technology, contributing to ultralow power consumption and inherent robustness.

The SN65LBC174 and SN75LBC174 provide both positive and negative current limiting and thermal shutdown to protect the transmission bus from line fault conditions. These devices deliver excellent performance when used with the SN75LBC173 or SN75LBC175 quadruple line drivers. The SN75LBC174 operates over a commercial temperature range of 0°C to 70°C. The SN65LBC174 operates over an industrial temperature range of -40°C to 85°C.
