Description

The MAX485ECSA+T is a low-power, half-duplex RS-485/RS-422 transceiver designed for robust data communication in industrial applications. It operates over a wide voltage range of 3.0V to 5.5V, making it suitable for various electronic systems. The device supports data rates up to 2.5 Mbps, ensuring fast communication over long distances—up to 4000 feet (1200 meters) at lower speeds.
Key features include its ability to drive up to 32 transceivers on a single bus and its improved power efficiency, which significantly reduces power consumption compared to older models. The MAX485ECSA+T is housed in a compact 8-pin SOIC package, making it ideal for space-constrained applications.
This transceiver is commonly used in multi-point communications, such as in field buses, industrial control, and data acquisition systems, where reliable, long-distance data transmission is critical. Its ease of integration and robust performance make it a popular choice among engineers.

Features

The MAX485ECSA+T is a low-power, half-duplex RS-485/RS-422 transceiver. Key features include:
1. Data Rate: Supports data rates up to 2.5 Mbps.
2. Distance: Capable of communication over distances up to 4000 feet (1200 meters) at lower speeds.
3. Operating Voltage: Operates from a single 5V supply.
4. Low Power Consumption: Typically consumes 120 µA in shutdown mode and 500 µA during operation.
5. High Noise Immunity: Provides excellent noise immunity due to its differential signaling.
6. Thermal Shutdown: Includes built-in thermal protection.
7. Bus Termination: Supports up to 32 transceivers on the bus.
8. Pin Configuration: Available in a compact 8-pin DIP or SOIC package.
These features make the MAX485ECSA+T suitable for industrial automation, telecommunications, and data acquisition applications where robust and reliable communication is essential.

Package

The MAX485ECSA+T is offered in an 8-pin SOIC (Small Outline Integrated Circuit) package. This surface-mount package type is designed for ease of integration into electronic circuits while providing efficient performance in RS-485/RS-422 communication applications.

Pinout

The MAX485ECSA+T is an integrated circuit used for RS-485 and RS-422 communication. It features a total of 8 pins. The pin configuration and their functions are as follows:
1. RO (Receiver Output): Outputs the received data.
2. RE (Receiver Enable): Active low; enables the receiver when low.
3. DE (Driver Enable): Active high; enables the driver when high.
4. DI (Driver Input): Inputs the data to be transmitted.
5. A (Non-Inverting Input): Positive input for the differential signal.
6. B (Inverting Input): Negative input for the differential signal.
7. VCC: Power supply pin (typically +5V).
8. GND: Ground reference pin.
The MAX485ECSA+T facilitates low-power and balanced transmission over long distances, making it suitable for industrial applications.
