Feature: 1. Bi-Directional Isolation: This module features an ISO1540 bidirectional isolator that allows electrical isolation of two devices communicating through an I2C interface. It provides 2500 V-RMS isolation, ensuring reliable and safe communication between different devices. 2. High-Speed Communication: The module supports up to 1 MHz communication, which ensures smooth and efficient data transfer between various devices. 3. Open-Drain Outputs: The first side has a sink current capability of 3.5 mA, while the second side has a sink current capability of 35 mA. These open-drain outputs easy to connect to different devices without any compatibility issues. 4. Wide Temperature Range: With a working temperature range from -40°C to +125°C, this module is ideal for use in a wide range of applications, even in harsh environments. ESD Protection: All pins have HBM 4 kV ESD protection, while the bus pins provide 8 kV protection, protecting the module from electrostatic discharge. It also comes with a STEMMA QT connector, making it easy to connect to different devices.
