Texas Instruments TXU0202 Voltage-Level Translator is a 2-bit, dual-supply non-inverting fixed-direction voltage level translation device. Ax pins are referenced to the VCCA logic level, an OE pin can be referenced to either VCCA or VCCB logic levels, and a Bx pin is referenced to the VCCB logic levels. The A port can accept input voltages ranging from 1.1V to 5.5V, while the B port can also accept input voltages from 1.1V to 5.5V. Fixed direction data transmission can occur from A to B when OE is set to high in reference to either supply. When OE is set to low on the Texas Instruments TXU0202, all output pins are in the high-impedance state.

Features

  • A 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: TXU0102
  • Operating temperature from –40°C to +125°C
  • Latch-up performance exceeds 100mA per JESD 78, class II
  • ESD protection exceeds JESD 22
    • 2500V human-body model
    • 1500V charged-device model
