SN65LBC174 四路低功耗差动线路驱动器
              
The SN65LBC174 and SN75LBC174 are monolithic, quadruple, differential line   drivers with 3-state outputs. Both devices are designed to meet the requirements   of the Electronics Industry Association Standard EIA-485. These devices are   optimized for balanced multipoint bus transmission at data rates up to and   exceeding 10 million bits per second. Each driver features wide positive and   negative common-mode output voltage ranges, current limiting, and   thermal-shutdown protection, making it suitable for party-line applications in   noisy environments. Both devices are designed using LinBiCMOSTM, facilitating   ultralow power consumption and inherent robustness.
              Both the SN65LBC174 and SN75LBC174 provide positive- and negative-current   limiting and thermal shutdown for protection from line fault conditions on the   transmission bus line
