The SP3485EIM/TR is a SOP-8, RoHS-Compliant RS-485/RS-422 IC (Integrated Circuit) manufactured by HGSemi. It is an over-voltage tolerant, low power, low EMI, single-channel transceiver designed for RS-485 and RS-422 applications. It features a variety of functions for enhanced anti-interference, such as slew rate control, pre-emphasis, and common-mode filtering. The SP3485EIM/TR has an operating voltage range from 3.0V to 3.6V, and is capable of running with a wide range of baud rates. It also features a wide common mode input voltage range, allowing for greater system flexibility. The SP3485EIM/TR comes in an 8-pin SOP (small outline package) with an operating temperature range of -40°C to 85°C.
