Digital Isolators

ISO7241ADW Description

The ISO7241ADW from Texas Instruments is a high-performance, quad-channel digital isolator designed for robust signal isolation in industrial and automotive applications. Utilizing capacitive coupling technology, it delivers reliable isolation up to 4000Vpk with a data rate of 1Mbps, making it suitable for high-speed communication interfaces. This unidirectional isolator operates from a 3.15V to 5.5V supply, ensuring compatibility with mixed-voltage systems. With a common-mode transient immunity (CMTI) of 25kV/µs, it excels in noisy environments, minimizing signal integrity issues. The device is housed in a 16-SOIC package and is RoHS3 compliant, meeting stringent environmental standards.

ISO7241ADW Features

• High Isolation Voltage: 4000Vpk ensures robust protection in high-voltage systems.
• Fast Signal Transmission: Propagation delay of 95ns max and rise/fall times of 2ns enable high-speed data transfer.
• Low Distortion: Pulse width distortion limited to 10ns for accurate signal replication.
• Wide Supply Range: Operates from 3.15V to 5.5V, supporting mixed-voltage designs.
• High Noise Immunity: 25kV/µs CMTI ensures reliable performance in electrically noisy environments.
• Compact & Reliable: 16-SOIC package with MSL 2 (1 Year) moisture sensitivity for long-term reliability.

ISO7241ADW Applications

• Industrial Automation: Isolate PLCs, motor drives, and sensors to prevent ground loops and noise interference.
