Voltage Level Translators

NXP's voltage level translators serve as an interface between different supply and input/output voltage levels

Image of NXP's Voltage Level TranslatorsNXP Semiconductors offer a large selection of I2C voltage translators to address the various applications that need a transition of I2C signals through multiple voltage domains without direct control.

There are three different types of devices:

  • FET for low capacitance applications
  • FET with internal one shot for mid (100 pF to 300 pF) capacitance applications
  • Active buffer with two supply pins for high (200 pF to 540 pF) capacitance applications
