概述

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

The MAX487EESA+T is a low-power, differential bus transceiver designed for RS-485 and RS-422 communication standards. Key features include:

2. High Data Rate: Supports data rates up to 2.5 Mbps, making it suitable for fast communication applications.
3. Differential Output: Provides robust differential signaling, improving noise immunity over long distances.
4. Multiple Driver / Receiver Configuration: Allows up to 32 transceivers on the bus, facilitating multi-point communication.
5. Thermal Protection: Incorporates thermal shutdown to enhance reliability.
6. Wide Operating Temperature Range: Rated for -40°C to +85°C, suitable for industrial applications.
7. Fail-Safe Design: Ensures a known state when the bus is floating or terminated incorrectly.
These features make the MAX487EESA+T ideal for various applications, including industrial automation, data acquisition, and remote sensor networks.

Package

The MAX487EESA+T comes in an 8-pin SOIC (Small Outline Integrated Circuit) package.

Pinout

The MAX487EESA+T is a low-power, half-duplex RS-485/RS-422 transceiver that features a pin count of 8.
Pin Functions:
1. A: Non-inverting terminal for the differential signal.
2. B: Inverting terminal for the differential signal.
3. RO (Receiver Output): Outputs the received data from the RS-485/RS-422 bus.
4. RE (Receiver Enable): Active low input to enable the receiver; high disables the receiver.
5. DE (Driver Enable): Active high input to enable the driver; low disables the driver.
6. DI (Driver Input): Inputs the data to be transmitted onto the RS-485/RS-422 bus.
7. VCC: Power supply pin (typically +5V).
8. GND: Ground pin.
