MAX3485ESA Description

Short technical summary and product information.

The MAX3485ESA is a low-power, 3.3V transceiver designed for RS-485 and RS-422 communication. It features one driver and one receiver, supporting half-duplex communication at data rates up to 10Mbps. This device is interoperable with +5V logic and operates over a wide common-mode input voltage range of -7V to +12V.

 

Key electrical characteristics include a supply voltage range of 3V to 3.6V and a typical receiver hysteresis of 50mV. The transceiver includes driver overload protection through current-limiting and thermal shutdown circuitry. It also features a receiver fail-safe function that guarantees a logic-high output if both inputs are open circuit.

 

The MAX3485ESA is available in an 8-SOIC package with surface mount mounting type. It operates within an industrial temperature range of -40°C to 85°C. This component is suitable for applications requiring reliable RS-485/RS-422 communication, such as telecommunications and industrial control local area networks.
