ADM485JRZ - High-Speed, Low-Power, RS-485/RS-422 Transceiver

The ADM485JRZ is a robust differential line transceiver from the renowned manufacturer Analog Devices Inc., designed to facilitate high-speed bi-directional communication on multipoint bus transmission lines. It is compliant with the EIA-485 and RS-422 standards, making it an ideal choice for industrial applications where a reliable and efficient data transmission is required.

This transceiver is capable of data rates up to 5 Mbps, ensuring rapid data exchange which is essential for modern industrial networks. The ADM485JRZ operates from a single 5 V power supply and features a low-power shutdown mode that reduces the supply current to a mere 10 nA, maximizing efficiency in power-sensitive applications.

Engineered with a half-duplex configuration, the ADM485JRZ includes a differential line driver and a differential line receiver. Both the driver and the receiver can handle up to 32 transceivers on the bus, which means that the device can support complex network topologies with multiple nodes. Its tri-state driver and receiver outputs remain in a high impedance state when the device is deactivated or when the power is off, preventing any potential damage to the bus lines.

The ADM485JRZ is characterized by its thermal shutdown and current limiting features, which provide protection against faulty wiring or excessive power dissipation. This makes the device particularly resilient in harsh industrial environments. Additionally, it has a wide common-mode voltage range, making it suitable for multi-point applications over long cable runs.

Available in an 8-lead SOIC package, the ADM485JRZ is designed for space-constrained applications. It is also fully specified over the industrial temperature range of -40°C to +85°C, ensuring reliable operation in extreme conditions.

Whether it's for factory automation, process control systems, or other industrial data communication needs, the ADM485JRZ from Analog Devices Inc. provides a high-performance, reliable solution for your RS-485/RS-422 communication requirements.
