Overview

Description

The MAX481ESA+ is a low-power, high-speed transceiver designed for RS-485 and RS-422 communication. It features a differential signaling approach, which enhances noise immunity and allows for long-distance data transmission (up to 4000 feet). The device operates with a supply voltage range of 3.0V to 5.25V and consumes minimal power, making it suitable for battery-powered applications.
Key features include a slew rate of 30 V/μs, enabling high-speed data rates up to 2.5 Mbps, and a built-in fail-safe that ensures a known state during power-down. The MAX481ESA+ supports half-duplex communication, making it ideal for applications like industrial automation, remote sensing, and data acquisition systems.
The device is housed in an 8-pin SOIC package, facilitating easy integration into various circuit designs. Its robust performance, low power consumption, and reliability make the MAX481ESA+ a popular choice for engineers working with serial communication protocols.

Features

The MAX481ESA+ is a low-power, RS-485/RS-422 transceiver designed for robust communication in harsh environments. Key features include:
- Data Rate: Supports data rates up to 2.5 Mbps.
- Power Consumption: Low power operation with a typical supply current of 120 µA in standby mode.
- Operating Range: Wide voltage range from +3.0V to +5.5V.
- Driver/Receiver: Full-duplex operation with one driver and one receiver.
- Line Length: Suitable for long-distance communication up to 4000 feet.
- Thermal Protection: Built-in thermal shutdown for reliability.
- ESD Protection: Enhanced ESD protection to ±15 kV (contact) and ±30 kV (air) for improved reliability.
- Pin Configuration: Standard 8-pin DIP or SOIC package for easy integration.
- Fail-Safe: Input fail-safe feature to ensure the receiver outputs a known state when the inputs are open or shorted.
These features make the MAX481ESA+ ideal for industrial applications, automation, and data acquisition systems requiring robust communication.

Package
