Notes
2. Test conditions assume a signal transition time of 10 ns or less, timing reference levels of 0.5 × VDD, input pulse levels of 0 to 3 V, output loading of the specified
IOL/IOH and load capacitance shown in AC Test Conditions on page 8.
3. tHZ and tOHZ are specified with a load capacitance of 5 pF. Transition is measured when the outputs enter a high impedance state.
4. This parameter is characterized but not 100% tested.
