DollaTek ISO1540 Bi-directional I2C Insulator to add full electrical insulation between the two ends of the I2C bus

Features Isolated bi-directional, I2C compatible communication. Supports operations up to 1 MHz. Power supply range from 3V to 5.5V The open-drain output has 3.5mA side 1 and 35mA side 2 sink current capabilities. Operating temperature from -40°C to +125°C. ±50 kV/μs transient immunity (typical) HBM ESD protection on all pins is 4kV; the bus pin has a voltage of 8 kV. Package includes: 1 x module

Product Features

• You can add full electrical insulation between the two ends of the I2C bus by using the ISO1540 I2C bi-directional insulator.
• The TI ISO1540 is fully bi-directional, supports clock speeds up to 1MHz, supports clock stretching, works with 3 to 5V DC or logic and has 2500V RMS isolation.
• You can get power/ground/clock/data disconnect pads for each side as well as a matching STEMMA QT connector.
• We have 10,000 extracts on each side from the I2C pin to the corresponding VCC.
• STEMMA QT ports on both sides are compatible with SparkFun I2C connectors.
