概述

Description

The MAX487CSA+ is a low-power, half-duplex RS-485/RS-422 transceiver designed for reliable communication in multipoint applications. It features a maximum data rate of 2.5 Mbps and operates from a single 5V supply, consuming only 120 µA in low-power mode, which makes it suitable for battery-operated devices.
The device supports a common-mode voltage range of -7V to +12V, allowing for robust communication over longer distances and in noisy environments. It includes a fail-safe feature that ensures the receiver outputs a high logic level when the input is left floating or if the network is idle.
The MAX487CSA+ is housed in a standard DIP package, making it easy to integrate into various circuit designs. With its capabilities, it is commonly used in industrial automation, data acquisition systems, and remote sensor applications, providing a cost-effective solution for long-distance serial communication.

Features

The MAX487CSA+ is a low-power, dual RS-485/RS-422 transceiver designed for high-speed communication over long distances. Key features include:
1. Dual-Channel Design: Supports both half-duplex and full-duplex communication.
2. Low Power Consumption: Operates with a low supply current, making it suitable for battery-powered devices.
3. High-Speed Data Rates: Capable of data rates up to 2.5 Mbps, facilitating fast data transmission.
4. Wide Operating Voltage: Supports a power supply range of 3.0V to 5.5V.
5. Short-Circuit Protection: Built-in protection against short circuits and thermal shutdown.
6. Fail-Safe Feature: Ensures a known state during power-down or idle conditions, preventing erroneous data.
7. Extended Temperature Range: Operates safely in environments from -40°C to +85°C.
8. Compact Package: Available in a small SOIC package, simplifying PCB design and placement.
These features make the MAX487CSA+ ideal for industrial automation, telecommunications, and any application requiring robust serial communication.

Package

The MAX487CSA+ is packaged in a 14-PDIP (Plastic Dual In-Line Package) format. This package type features a standard dual in-line configuration suitable for through-hole mounting on PCBs.

Pinout

The MAX487CSA+ is a low-power, half-duplex RS-485/RS-422 transceiver with a pin count of 8. Its primary functions include:
1. Driver Output (A, B): Transmits differential signals for long-distance communication.
2. Receiver Input (A, B): Receives differential signals and converts them to single-ended logic levels.
3. Enable/Disable Pin (DE, RE): Controls the driver and receiver operation; DE enables the driver, while RE disables the receiver.
4. Power Supply (Vcc): Provides power to the device.
5. Ground (GND): Common ground reference for the device.
The transceiver operates over a wide voltage range and is designed for applications requiring robust data transmission over long distances, such as in industrial automation and telecommunications.
