The SN65HVD485E is a half-duplex transceiver designed for RS-485 data bus networks. Powered by a 5V supply, it is fully compliant with the TIA/EIA-485A standard. This device is suitable for data transmission up to 10Mbps over long twisted-pair cables and is designed to operate with very low supply current, typically less than 2mA, exclusive of the load. When in the inactive shutdown mode, the supply current drops below 1mA.
The wide common-mode range and high ESD protection levels of this device make it suitable for demanding applications such as, electrical inverters, status/command signals across telecom racks, cabled chassis interconnects, and industrial automation networks where noise tolerance is essential. The SN65HVD485E matches the industry-standard footprint of the SN75176. Power-on reset circuits keep the outputs in a high-impedence state until the supply voltage has stabilized. A thermal shutdown function protects the device from damage due to system fault conditions. The SN65HVD485E is characterized for operation from -40°C to 85°C air temperature.
