Notes
8. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V and output loading of the specified IOL/IOH,
and 30 pF load capacitance.
9. AC test conditions use VOH = 1.6V and VOL = 1.4V.
10. At any given temperature and voltage condition for any given device, tHZCE is less than tLZCE and tHZOE is less than tLZOE.
11. tLZCE, tLZWE, tHZOE, tLZOE, tHZCE, and tHZWE are tested with CL = 5pF as in (b) of AC Test Loads and Waveforms. Transition is measured ± 500 mV from steady state
voltage.
