SN75LBC174DWRG4

RS-485接口IC Quad Low-Pwr Diff Line Driver

description

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 LinBiCMOS, facilitating ultralow power consumption and inherent robustness.
