9.2.2 Detailed Design Procedure

To begin the design process, determine the following:

  • Input voltage range
    • Use the supply voltage of the device that is driving the TXS0108W-Q1 device to determine the input voltage range. For a valid logic high the value must exceed the VIH of the input port. For a valid logic low the value must be less than the VIL of the input port.
  • Output voltage range
    • Use the supply voltage of the device that the TXS0108W-Q1 device is driving to determine the output voltage range.
    • The TXS0108W-Q1 device has smart internal pull-up resistors. External pull-up resistors can be added to reduce the total RC of a signal trace if necessary.
  • An external pull-down resistor decreases the output VOH and VOL. Use Equation 1 to calculate the VOH as a result of an external pull-down resistor.
    Equation 1. VOH = VCCx × RPD / (RPD + 4kΩ)
