概要

Description

The MAX487EESA+T is a low-power, half-duplex RS-485/RS-422 transceiver designed for communication in industrial and automotive environments. It operates from a single 5V power supply and features a low supply current of just 120 µA, making it suitable for battery-powered applications. The device can transmit data at speeds up to 2.5 Mbps over long distances, supporting cable lengths of up to 4000 feet.
The MAX487EESA+T includes a built-in fail-safe feature that ensures a valid output state even when the inputs are floating. It supports a wide temperature range, making it reliable in various operating conditions. The transceiver is housed in a 8-Pin SOIC package, facilitating easy integration into compact circuit designs.
Overall, the MAX487EESA+T is ideal for multi-point data transmission in applications such as remote sensors, industrial control systems, and data acquisition systems.

Features
