2.3.6 TXU0204-Q1

TXU0204-Q1 (wireless operation) features a 4-bit, dual-supply non-inverting fixed direction voltage level translation device. Ax pins reference VCCA logic level, OE pin can reference VCCA and VCCB logic levels, and Bx pins reference VCCB logic levels. The A port accepts input voltages ranging from 1.1V to 5.5V, while the B port accepts input voltages from 1.1V to 5.5V. Fixed direction data transmission occurs from A to B and B to A when OE sets to high in reference to either supply. When OE is set to low, all output pins are in the high-impedance state.

Key features of the TXU0204-Q1 include:

  • AEC-Q100 qualified for automotive applications
  • Available in wettable flank QFN (WBQA) package
  • 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 allows for slow and noisy inputs
  • Inputs with integrated static pulldown resistors prevent channels from floating
  • High drive strength (up to 12mA at 5V)
  • Low power consumption:
    • 3µA 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 other variants that support common applications: TXU0104-Q1, TXU0304-Q1
  • 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
