MAX3485EESA+

The MAX3485EESA+ is a low-power, ±15kV ESD-protected transceiver from Analog Devices / Maxim Integrated, suitable for RS-485 and RS-422 communication applications. This device features a single driver and receiver, operating from a 3V to 3.6V supply. It supports half-duplex communication and guarantees a data rate of up to 12Mbps.

The transceiver is designed for reliable data transmission, minimizing EMI and reflections with slew-rate limiting for error-free communication. It includes enhanced electrostatic discharge (ESD) protection on its I/O pins, rated up to ±15kV using the Human Body Model. The device also features short-circuit current limiting and thermal shutdown for driver overload protection. The receiver input has a fail-safe feature that ensures a logic-high output if both inputs are open circuit.

Packaged in an 8-SOIC form factor, the MAX3485EESA+ is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for various industrial and telecommunications environments. The device also offers a low-current shutdown mode, consuming only 2nA.

Applications for this transceiver include industrial control, local area networks, telecommunications, and EMI-sensitive applications. Its interoperability with +5V logic further enhances its design flexibility.
