MAX3485ESA Description

Short technical summary and product information.

The MAX3485ESA from UMW (Youtai Semiconductor) is a 3.3V low-power transceiver for RS-485 and RS-422 communication. This device features a single driver and receiver, supporting half-duplex communication at data rates up to 12Mbps. It is designed to operate from a single 3.3V supply, making it interoperable with +5V logic systems.

 

The transceiver is suitable for EMI-sensitive applications and industrial-control local area networks. It includes features such as current-limiting and thermal shutdown for driver overload protection, and a fail-safe receiver input that guarantees a logic-high output if both inputs are open circuit. The MAX3485ESA is available in an 8-SOIC package and is designed for surface mount applications.

 

Key electrical specifications include a supply voltage range of 2.97V to 3.63V and a receiver hysteresis of 30mV. The operating temperature range is -40°C to 85°C. The device supports up to 32 transceivers on the bus and is compliant with RoHS3 standards.
