SP3485EN Description

Short technical summary and product information.

The SP3485EN from Exar is a 3.3V low-power half-duplex transceiver designed to meet the specifications of the RS-485 and RS-422 serial protocols. This device is capable of supporting data rates up to 10 Mbps under load, making it suitable for various industrial communication applications.

 

Key electrical characteristics include a supply voltage range of 3V to 3.6V and receiver hysteresis of 20 mV. The transceiver utilizes differential signaling for long-distance data exchange. In transmit mode, it converts single-ended TTL logic levels to differential signals (A and B lines). In receive mode, a high-sensitivity differential receiver restores these signals to standard TTL levels. The device features DE (Driver Enable) and RE (Receiver Enable) control pins for rapid switching between transmit and receive states, ideal for multi-node bus environments.

 

The SP3485EN is housed in an 8-SOIC package and is designed for surface mounting. Its operating temperature range is -40°C to 85°C. The integrated ESD protection ensures robustness in demanding conditions. This transceiver is pin-to-pin compatible with other industry standards, facilitating integration into existing designs.
