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 SN74AXCH4T245 device to determine the input voltage range. For a valid logic-high, the value must exceed the high-level input voltage (VIH) of the input port. For a valid logic low the value must be less than the low-level input voltage (VIL) of the input port.
- Output voltage range
- Use the supply voltage of the device that the SN74AXCH4T245 device is driving to determine the output voltage range.
