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 TXB0304 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 TXB0304 device is driving to determine the output voltage range.

- Don’t recommend to have the external pull-up or pull-down resistors. If mandatory, it is recommended the value should be larger than 20 kΩ.

• An external pull-down or pull-up resistor decreases the output VOH and VOL. Use the below equations in section 8.5.2 to draft estimate the VOH and VOL as a result of an external pull-down and pull-up resistor.
