MAX3487 3–3.6V RS-485 Transceiver IC | Slew-Rate Limited, Low Power, Half-Duplex, DIP/SOP Package | Xinbole

The MAX3487 is a low-power RS-485 transceiver IC designed for reliable differential communication in low-voltage embedded and industrial systems. Built using advanced CMOS interface technology, it combines efficient power consumption, controlled switching performance, and strong noise immunity to ensure stable data transmission in demanding environments.

Operating within a supply voltage range of 3V to 3.6V, the MAX3487 provides a clear advantage for battery-powered and low-power applications compared to traditional 5V RS-485 transceivers. A key feature of this device is its slew-rate limited driver, which reduces electromagnetic interference (EMI) and minimizes signal reflections, making it ideal for longer cable runs and noise-sensitive systems.

The transceiver supports half-duplex communication, enabling bidirectional data transfer over a single differential pair, simplifying wiring and reducing system complexity. Its low quiescent current and optimized thermal performance contribute to improved energy efficiency and long-term reliability in continuous operation.

Available in both DIP and SOP package types, the MAX3487 offers flexibility for prototyping, compact PCB designs, and scalable manufacturing.
