Benefits of our Auto-direction translators

Auto-direction voltage translators are available in dual supply configurations. Yet unlike the direction-controlled voltage translators they automatically sense the direction of the signal without the need for a direction control pin.  There are a number of trade-offs including drive-strength, data rate, and multi-voltage translation. The wide range of functionalities provide options to fit every design need.

  • Works with bi-directional signals. 
  • Devices available that have been optimized for common interfaces. 
  • Works with both open-drain and push-pull interfaces. 
  • Design flexibility with external pull-up resistors.
  • Open Drain use cases include: I2C, MDIO, SMBUS, GPIO
  • Push Pull use cases include: GPIO, SPI, UART, JTAG, I2S, RGMII

Benefits of our Direction-controlled translators

Direction-Controlled voltage translators perform non-inverting up or down translation of a uni-directional signal. These have one or more direction control pins that allow the designer to configure which pins are inputs and outputs. This enables simultaneous up and down translation on one device and gives more flexibility. Many devices feature Bus Hold, which retains the last known state of the output when the inputs are floating or high impedance. Bus Hold is indicated by “H” in the part number. 

  • Push Pull buffered output for high drive strength. 
  • One or more direction control pins. 
  • Devices available that have been optimized for common interfaces. 
  • Bus Hold functionality available.
  • Use cases include: SPI, UART, JTAG, GPIO, I2S, RGMII
