The SN65HVD485E is a half-duplex transceiver designed for RS-485 data bus networks. Powered by a 5-V supply, it is fully compliant with the TIA/EIA-485A standard. This device is suitable for data transmission up to 10 Mbps over long twisted-pair cables and is designed to operate with very low supply current, typically less than 2 mA, exclusive of the load. When in the inactive shutdown mode, the supply current drops below 1 mA. 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 -40C to 85C air temperature.
