Overview
The SN65HVD1176DR is a half-duplex differential transceiver optimized for use in PROFIBUS (EN 50170) and RS-485 applications. Produced by Texas Instruments, this device is designed to meet the stringent requirements of high-speed data transmission across twisted-pair networks. It features a signaling rate of up to 40 Mbps, making it suitable for high data-transfer speeds. The transceiver is characterized by its low bus capacitance, which minimizes signal distortion, and its ability to support up to 160 nodes on a single bus.
