Digital Isolators

I2C isolatorBidirectional I2CReinforced isolationHot swapSOIC-16 wide

ISO1640DWR is a 16-pin wide-SOIC reinforced-isolation I2C isolator for systems requiring bidirectional SDA and SCL isolation up to 1.7 MHz.

Best for

  • Isolated I2C controller-to-bus connections
  • Industrial control interfaces
  • Battery management and power-management buses

Avoid if

  • The interface requires more than 1.7 MHz operation
  • The controller-side I2C node exceeds 80 pF capacitance
  • A non-isolated I2C connection is sufficient

Check before use

  • Confirm VCC1 is 3 V to 5.5 V and VCC2 is 2.25 V to 5.5 V
  • Keep side-1 pull-up current within 3.5 mA
  • Validate the applicable reinforced-insulation requirements
