Texas Instruments TXU0102 Dual-Bit Voltage-Level Translator

Texas Instruments TXU0102 Dual-Bit Fixed Direction Voltage-Level Translator features flexible pin configurations. The Ax pins are referenced to the VCCA logic level, the OE pin can be referenced to either VCCA or VCCB logic levels, and Bx pins are referenced to VCCB logic levels. The A port accepts input voltages ranging from 1.1V to 5.5V, while the B port also accepts input voltages from 1.1V to 5.5V. The fixed direction data transmission occurs from A to B or B to A when OE is set to high in reference to either supply. When OE is set to low, all output pins are in the high-impedance state.


  • Fully configurable dual-rail design allows each port to operate from 1.1V to 5.5V
  • Up to 200Mbps support for 3.3V to 5.0V
  • Schmitt-trigger inputs allow for slow and noisy inputs
  • Inputs with integrated static pull-down resistors prevent channels from floating
  • High drive strength (up to 12mA at 5V)
  • Low power consumption
    • 2.5µA maximum (25°C)
    • 6µA maximum (–40°C to 125°C)
  • VCC isolation and VCC disconnect (Ioff-float) feature
    • If either VCC input is <100mV or disconnected, all outputs are disabled and become high impedance
  • Ioff supports partial-power-down mode operation
  • Control logic (OE) with VCC(MIN) circuitry allows for control from either A or B port
  • Pinout compatible with TXB family level shifters
  • Available in another variant that supports common applications: TXU0202
  • Operating temperature from –40°C to +125°C
  • Latch-up performance exceeds 100 mA per JESD 78, class II
  • ESD protection exceeds JESD 22
    • 2500V human-body model
    • 1500V charged-device model


  • Eliminate slow or noisy input signals
  • Driving indicator LEDs or buzzers
  • Debouncing a mechanical switch
  • General purpose I/O level shifting
  • Push-pull level shifting (UART, SPI, JTAG, and so forth)
