MAX3490ECSA Description

Short technical summary and product information.

The MAX3490ECSA from Analog Devices is a high-performance transceiver designed for robust RS485 and RS422 communication systems. This device supports full-duplex communication, enabling simultaneous data transmission and reception.

 

Key electrical specifications include operation from a single +3.3V supply, a guaranteed data rate of up to 12Mbps, and a wide common-mode input voltage range of -7V to +12V. It features enhanced electrostatic discharge (ESD) protection on its I/O pins, rated for ±15kV using the Human Body Model and IEC 1000-4-2 standards.

 

The transceiver includes drivers that are short-circuit current limited and protected by thermal shutdown circuitry. The receiver input has a fail-safe feature ensuring a logic-high output when inputs are open. The MAX3490ECSA is housed in a compact 8-pin SOIC package, suitable for surface mount applications.

 

This transceiver is ideal for applications requiring reliable serial communication in industrial, telecommunications, and local area network environments, particularly where EMI sensitivity is a concern.
