概述

Description

The ADM3077EARZ is a high-speed, isolated RS-485/RS-422 transceiver designed for robust communication in industrial and data acquisition environments. It features integrated isolation, allowing for safe data transmission across different voltage domains, which is crucial for preventing damage in electrically noisy settings. The device supports data rates of up to 50 Mbps and is designed for half-duplex communication.
Key features include a wide operating temperature range, low power consumption, and a compact package suitable for space-constrained applications. The ADM3077EARZ also includes protection against electrostatic discharge (ESD) and supports a variety of power supply configurations, enhancing its versatility. This transceiver is ideal for applications in factory automation, process control, and remote sensor networks, where reliable and high-speed data transmission is essential.

Features

The ADM3077EARZ is a high-speed, low-power RS-485/RS-422 transceiver designed for reliable data communication over long distances. Key features include:
1. Data Rate: Supports data rates up to 250 kbps.
2. Supply Voltage: Operates from a single 3.3V to 5V supply.
3. Low Power Consumption: Typically consumes only 120 µA in low-power sleep mode.
4. High Noise Immunity: Features a common-mode range from -7V to +12V, enhancing noise margin.
5. Transmitter/Receiver Enable Control: Allows for easy management of power and communication states.
6. Fail-Safe Design: Ensures the receiver outputs a known state when inputs are open or shorted.
7. ESD Protection: Provides robust ESD protection, making it suitable for industrial applications.
8. Pin Compatibility: Compatible with other industry-standard transceivers for easy integration.
These features make the ADM3077EARZ an ideal choice for applications requiring robust, high-speed data transmission over twisted-pair cables.

Package

The ADM3077EARZ is packaged in a 16-lead TSSOP (Thin Shrink Small Outline Package) form factor.

Pinout

The ADM3077EARZ is a high-speed, isolated RS-485/RS-422 transceiver with 8 pins. Its primary functions include enabling robust serial communication over long distances while maintaining electrical isolation between different parts of a system.
The pin configuration is as follows:
1. A - Non-inverting input/output for the differential signal.
2. B - Inverting input/output for the differential signal.
3. GND - Ground reference for the device.
4. VDD - Power supply pin.
5. RO - Receiver output, providing the received data.
6. DI - Driver input, accepting the data to be transmitted.
7. RE - Receiver enable, controlling the activation of the receiver.
8. DE - Driver enable, controlling the activation of the driver.
The ADM3077EA operates over a wide voltage range and is designed for applications requiring high-speed data transmission with noise immunity.
