The ISO35DW from Texas Instruments is a robust, high-performance isolated differential line driver and receiver that operates with a single 3.3V or 5V power supply. This device is designed to meet the demanding requirements of industrial communication systems, providing reliable data transmission even in harsh environments.
At the heart of the ISO35DW lies its isolation technology, which separates the logic input and output sides to protect against high voltage spikes and surges typically found in industrial settings. This isolation ensures that data signals are transmitted accurately while the rest of the system is safeguarded from electrical noise and transient voltage events.
Key Features:
- Integrated isolation: The ISO35DW offers 2500 Vrms (1 minute) of galvanic isolation between the bus-line transceiver and the logic-level interface.
- High-speed operation: With signaling rates up to 20 Mbps, the device is suitable for high-speed data communication in industrial applications.
- Fail-safe receiver: The receiver inputs have a fail-safe feature that ensures a known logic high output if the inputs are open, shorted, or idle, providing additional system reliability.
- Wide temperature range: The device operates over an industrial temperature range of -40°C to +85°C, ensuring performance in extreme conditions.
- Robust electromagnetic compatibility (EMC): The ISO35DW is designed with low emissions and high immunity to meet stringent EMC requirements, reducing the risk of data corruption due to electrical noise.
Applications for the ISO35DW are diverse and include industrial fieldbus networks such as PROFIBUS, MODBUS, and other RS-485/RS-422 communication protocols. Its high level of integration and performance features make it an ideal choice for designers looking to improve communication reliability and protect their systems against the electrical challenges found in industrial environments.
Overall, the ISO35DW is a testament to Texas Instruments' commitment to providing high-quality, reliable components for the most demanding industrial applications. By integrating advanced features into a compact, efficient package, Texas Instruments ensures that your systems maintain high performance and durability.
