The SN65HVD3085EIM/TR is a RS-485/RS-422 IC manufactured by HGSEMI. It is a SOP-8 RoHS-compliant, ultra-low power EIA/TIA-485 and EIA/TIA-422 transceiver. It is designed to guarantee immunity to noise problems in communications up to 1.5 Mbps. It ensures an improved pin layout, lower system power consumption, and extends the distance of communication up to 1 km. It also integrate protection features such as thermal shutdown and crowbar shutdown. Its integrated transceivers feature line failure detections and conditions of false line, no dominant, and dominant detect circuits. It is suitable for different industrial communication protocol such as Modbus, Profibus, and DeviceNet. It is ideal for long-distance and noisy environments.
