Product Summary
The SN75LBC174DW is a monolithic, quadruple, differential line driver with 3-state outputs. It is designed to meet the requirements of the Electronics Industry Association Standard EIA-485. The SN75LBC174DW is 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. The SN75LBC174DW is designed using LinBiCMOSE, facilitating ultra-low power consumption and inherent robustness.
