MAX14781EESA+ Description

Short technical summary and product information.

The MAX14781EESA+ from Analog Devices (formerly Maxim Integrated) is a versatile half-duplex RS-485 transceiver designed for robust communication in demanding environments. It features automatic polarity correction, simplifying installation by autonomously correcting miswired A and B lines. The device supports data transmission up to 370kbps with slew-rate limited drivers to minimize EMI.

 

Key electrical specifications include a wide operating voltage range of 4.5V to 5.5V and a low shutdown current of 10µA maximum. The transceiver offers true fail-safe receiver circuitry, ensuring a logic-high output when inputs are open or shorted. Integrated ±25kV ESD protection using the Human Body Model enhances reliability.

 

This transceiver is housed in an 8-pin SOIC package, suitable for surface mount applications. It operates across an extended temperature range of -40°C to +85°C, making it ideal for industrial and control systems, power meter networks, and HVAC networks.
