I2C Isolator for Reliable Communication

The Adafruit ISO1540 Bidirectional I2C Isolator is a high-reliability bi-directional digital isolator that provides bidirectional isolation of two channels, making it an essential component for reliable communication between development boards and sensors. This device supports I2C clock frequencies up to 2MHz, with common mode transient immunity, and offers UL1577-qualified electrical isolated withstand voltage of 3.75kVrms.

The NSi8100NC features STEMMA QT connectors on either side, which are compatible with the SparkFun Qwiic I2C connectors, allowing for easy connections between development boards and sensors. The device also includes 10K pull-ups on each side, from the I2C pins to the matching VCC for that side.

The Adafruit ISO1540 Bidirectional I2C Isolator is designed to provide full electrical isolation between two sides of an I2C bus, making it ideal for applications where one side is Earth-grounded or requires reduced noise. This device supports up to 1MHz clock rates and works with 3 to 5V DC power or logic on either side.

With its bi-directional design and support for clock-stretching, the ISO1540 Isolator can be used to add full electrical isolation between two sides of an I2C bus. Whether you're working with a funky power monitoring setup or need to reduce noise on your I2C bus, this device is designed to provide reliable communication.

By using the Adafruit ISO1540 Bidirectional I2C Isolator, you can ensure that your development board and sensors are safely isolated from each other, allowing for trouble-free data transfer. With its high-reliability design and support for a wide range of applications, this device is an essential component for any project requiring reliable communication over an I2C bus.
