ADM1485ARZ Differential Bus Transceiver Half RS422, RS485 8-SOIC
The ADM1485ARZ from Analog Devices is a high-speed, low-power RS-485/RS-422 compliant differential bus transceiver designed for robust data transmission in noisy industrial environments. Housed in a compact 8-pin SOIC package, this integrated circuit operates from a single 5V power supply and features enhanced ESD protection of ±15kV, making it ideal for long-distance communication networks, industrial automation, and motor control systems. With its high immunity to electromagnetic interference and balanced differential line driving capability, the ADM1485ARZ ensures reliable data integrity over twisted-pair cables up to 10 Mbps, providing a robust solution for applications requiring secure and error-free serial communication.
Key Features
This transceiver features a proprietary low-power shutdown mode that reduces current consumption to less than 1μA, while maintaining receiver active state for network monitoring. It supports up to 256 nodes on a single bus with a wide common-mode voltage range of -7V to +12V, enabling reliable data transmission in electrically noisy environments. The device incorporates true fail-safe receiver inputs that ensure a logic-high output when inputs are open or shorted, eliminating the need for external bias networks. With a typical propagation delay of 20ns and skew of 2ns, the ADM1485ARZ maintains signal integrity in high-speed applications. Additional features include thermal shutdown protection, short-circuit current limiting, and compatibility with 3V/5V logic systems, ensuring robust performance across industrial temperature ranges (-40°C to +85°C).
