To begin the design process, determine the following:
- Input voltage range:
- Use the supply
voltage of the device that is driving the SN74AVCH8T245
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 SN74AVCH8T245 device is
driving to determine the output voltage range.
