MAX489ESD+T Description

Short technical summary and product information.

The MAX489ESD+T from Analog Devices is a low-power transceiver designed for RS-485 and RS-422 communication. Each part contains one driver and one receiver, supporting full-duplex communication. This transceiver operates from a single 5V supply and can transmit data at up to 2.5Mbps. It features reduced slew-rate drivers that minimize EMI and reduce reflections, allowing for error-free data transmission up to 250kbps.

 

Key electrical characteristics include a supply voltage range of 4.75V to 5.25V and an operating temperature range of -40°C to 85°C. The device draws between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Drivers are protected against excessive power dissipation by thermal shutdown circuitry.

 

Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount package, the MAX489ESD+T is suitable for various industrial control and EMI-sensitive applications. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.
