概要

Description

The MAX3483ESA+T is a low-power, half-duplex RS-485/RS-422 transceiver designed for multi-point data communications. It operates over a voltage range of 3.0V to 5.5V and supports data rates up to 250 kbps. This device is particularly suited for long-distance communication in noisy environments, making it ideal for industrial applications, automation systems, and building management.
The MAX3483 features a low quiescent current, allowing for battery-operated devices, and includes built-in fail-safe mechanisms to ensure reliable operation in the event of open circuits or shorted lines. Its small footprint and ease of integration make it suitable for space-constrained designs.
Key specifications include a wide common-mode voltage range, thermal shutdown protection, and a wide operating temperature range from -40°C to +85°C. The MAX3483 is available in an 8-pin SOIC package, facilitating easy incorporation into electronic designs.

Features

The MAX3483ESA+T is a low-power, half-duplex RS-485/RS-422 transceiver designed for data communication over long distances in noisy environments. Key features include:
1. Voltage Range: Operates from a single +3.0V to +5.5V supply.
2. Low Power Consumption: Consumes only 120 µA in inactive mode and 500 µA in active mode.
3. Data Rate: Supports data rates up to 250 kbps.
4. Distance: Capable of driving data lines up to 4000 feet at 100 kbps.
5. Thermal Shutdown: Includes thermal protection features.
6. Common Mode Range: Wide common-mode voltage range from -7V to +12V.
7. Fail-Safe Features: Built-in fail-safe mechanisms ensure a known output state under fault conditions.
8. ESD Protection: Provides extensive ESD protection up to ±15kV (contact) and ±30kV (air).
These features make the MAX3483ESA+T suitable for industrial applications and robust communication systems.

Package
