The MAX3490ECSA-T from Analog Devices is a +3.3V low-power transceiver designed for RS-485 and RS-422 communication. This device supports full-duplex communication and can transmit data at up to 12Mbps. It features enhanced electrostatic discharge (ESD) protection on its I/O pins, rated for ±15kV using the Human Body Model, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using IEC 1000-4-2 Air-Gap Discharge.
Drivers are protected against excessive power dissipation by thermal shutdown circuitry and are short-circuit current limited. The receiver input includes a fail-safe feature that guarantees a logic-high output if both inputs are open circuit. The MAX3490ECSA-T operates from a single +3.3V supply, eliminating the need for a charge pump, and is interoperable with +5V logic.
This transceiver is available in an 8-SOIC package and is suitable for surface mount applications. Its operating temperature range is 0°C to 70°C. Key applications include telecommunications, industrial control, local area networks, and EMI-sensitive applications.
