3.3V RS-485 Differential Transceiver IC for Low-Power Multipoint Communication Systems
The SN65HVD11DR is a robust RS-485 differential transceiver designed for reliable bidirectional communication across multipoint bus networks. Developed by Texas Instruments, this device integrates a three-state differential line driver and receiver, enabling efficient data transmission over balanced transmission lines.
Operating from a single 3.3 V supply, the SN65HVD11DR meets ANSI TIA/EIA-485-A and ISO 8482 standards, ensuring compatibility with industry-standard RS-485 communication systems. It features low standby current, wide common-mode voltage range, and high input impedance, allowing multiple devices to share the same bus with minimal loading. With flexible driver and receiver enable controls, the device supports easy direction control, making it ideal for industrial automation, building control systems, and embedded communication networks.
