Notes:
4. Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
5. All clock outputs loaded with 6" 60: traces with 22-pF capacitors.
6. W149 logic inputs have internal pull-up devices (pull-ups not full CMOS level).
