SP3485EN Description

Short technical summary and product information.

The SP3485EN-L/TR is a 3.3V low-power half-duplex transceiver that meets the specifications of the RS-485 and RS-422 serial protocols. This device is pin-to-pin compatible with popular industry standards and can achieve data rates up to 10 Mbps under load.

 

Utilizing differential signaling, the SP3485EN-L/TR converts single-ended TTL logic levels into differential signals for long-distance data exchange. Its high-sensitivity differential receiver detects minute voltage differences on the bus and restores them to standard TTL levels. The integrated DE (Driver Enable) and RE (Receiver Enable) control pins allow for rapid switching between transmit and receive states, making it suitable for multi-node industrial bus environments.

 

This transceiver operates over a supply voltage range of 3V to 3.6V and has a receiver hysteresis of 20 mV. It features integrated ESD protection and is specified for an operating temperature range of -40°C to 85°C. The device is supplied in an 8-SOIC package and is designed for surface mounting.
