MAX3488 3–3.6V RS-485 Transceiver IC | Slew-Rate Limited, Low Power, Half-Duplex, DIP/SOP Package | Xinbole

The MAX3488 is a low-power RS-485 transceiver IC engineered for reliable differential communication in low-voltage embedded and industrial systems. Built using advanced CMOS interface technology, it delivers stable performance with low power consumption, controlled switching characteristics, and high noise immunity, ensuring dependable operation in electrically noisy environments.

Operating within a supply voltage range of 3V to 3.6V, the MAX3488 offers a clear advantage over traditional 5V transceivers by enabling efficient integration into modern low-power and battery-operated systems. A key feature of this device is its slew-rate limited driver, which reduces electromagnetic interference (EMI) and signal reflections, making it especially suitable for longer cable runs and noise-sensitive applications.

The device supports half-duplex communication, allowing bidirectional data transmission over a single differential pair, simplifying system design and reducing wiring complexity. Its low quiescent current and optimized thermal characteristics enhance overall system efficiency and long-term reliability.

Available in both DIP and SOP package types, the MAX3488 provides flexibility for prototyping, compact PCB layouts, and scalable manufacturing.
