Notes:
8.
Tested initially and after any design or process changes that may affect these parameters.
9.
Unless otherwise noted, test conditions assume signal transition time of 2.5 ns or less, timing reference levels of 1.25V, input pulse levels of 0 to 2.5V, and
output loading of the specified IOL/IOH and load capacitance. Shown in (a) and (b) of AC test loads.
10. tCHZ, tCLZ, tEOHZ, and tEOLZ are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ± 200 mV from steady-state voltage.
11. At any given voltage and temperature, tCHZ (max) is less than tCLZ (min).
12. This parameter is sampled and not 100% tested.
