8.2.2 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 TXS0102V-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 TXS0102V-Q1 device is driving to determine the output voltage range.
    • The TXS0102V-Q1 device has 10kΩ internal pullup resistors. External pullup 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. V O H   =   V C C x   ×   R P D   /   R P D   + 10 k Ω  
  • Where:
  • VCCx is the supply voltage on either VCCA or VCCB
  • RPD is the value of the external pull down resistor
