I2C voltage translation and repeaters

Today's electronic systems are significantly more complex. This is clearly visible with the increased complexity found in I2C-bus communications. For I2C master/slave interfaces there is a trend towards higher bus speed (standard, Fast-mode, FM+), with multi-voltage bus branches common and a need for support of clock-stretching. Regardless of the complexity, Nexperia can offer a solution to meet your needs.

Design considerations

  • Potential for high capacitive bus load, handling FM+ speed (1 MHz)
  • I2C master and slaves operating from 0.8 V to 5 V
  • Need to split or separate I2C branches
  • Support for clock-stretching
