Notes

7. Test conditions assume a signal transition time of 5 ns or less, timing reference levels of 0.5 × VDD, input pulse levels of 10% to 90% of VDD, and output loading of

the specified IOL/IOH and 30 pF load capacitance shown in AC Test Conditions on page 12.

8. tOD and tHZ are specified with a load capacitance of 5 pF. Transition is measured when the outputs enter a high impedance state.

9. This parameter is characterized and not 100% tested.

10. Rise and fall times measured between 10% and 90% of waveform.

11. These parameters are guaranteed by design and are not tested.
