  • 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 pull-down 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

TXU0304-Q1 is a 4-bit, dual-supply noninverting fixed direction voltage level translation device. Ax pins are referenced to VCCA logic level, OE pin can be referenced to either VCCA or VCCB logic levels, and Bx pins are referenced to VCCB logic levels. The A port is able to 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 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. See Device Functional Modes for a summary of the operation of the control logic.
