Notes:

12. 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 I

and load capacitance. Shown in (a), (b) and (c) of AC test loads.

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.

14. At any given voltage and temperature, t

CHZ

(max.) is less than t

CLZ

(min.).

15. This parameter is sampled and not 100% tested.
