Voltage Level Translation

Broadest portfolio of general-purpose and performance level shifters

Voltage translators/level shifters are devices that resolve mixed voltage incompatibility between different parts of a system that operate in multiple voltage domains. They are common in today’s complex systems, especially when interfacing with legacy devices. TI offers the broadest portfolio of standard, general-purpose level-shifters spanning a wide range of voltages, frequencies, bit widths and IO types (open-drain or push-pull) along with performance-optimized application specific level shifters for standard interfaces (I2C, SD card, SIM card).


Unidirectional level shifters offer reliable one-way translation in a push-pull configuration.

  • 1, 2, 4, 16, 24, 32 bits
  • Push-pull IOs
  • 0.8V (min), 18V (max)
  • 275 MHz (max)


Bidirectional level shifters offer the flexibility and performance to solve any voltage level incompatibility.

  • 1, 2, 4, 6, 8 bits
  • Auto direction sense
  • Push-pull & open-drain IOs
  • 0.9V (min),5.5V (max)
  • 100 MHz (max)

Direction controlled

Direction controlled level shifters offer designers pin-point control over translation with a dedicated directional pin.

  • 1, 2, 4, 6, 8, 16, 24, 32 bits
  • Direction control pin
  • Push-pull IOs
  • 1.2 V (min), 5.5V (max)
  • 250 Mhz (max)


Logic level shifters integrate logic functionality and voltage translation into a single convenient, cost-effective, space-saving design.

  • 1, 4 bits
  • Logic input
  • Multiple logic functions
  • 0.8V (min), 5.5V (max)
  • 275 Mhz (max)

Application specific

Application-specific level shifters are capable of resolving many voltage level incompatibilities.

  • Audio Codec
  • CF card
  • Gunning translation
  • IC-USB
  • I2C
  • SD/MMC card
  • SIM card
  • UART
