Notes:
13. Input waveform should have a slew rate of > 2 V/ns.
14. Tested initially and after any design or process change that may affect these parameters.
15. Unless otherwise noted, test conditions assume signal transition time of 1.5ns, timing reference levels of 1.75V, input pulse levels of 0 to 3.3V, and output
loading of the specified I

are specified with AC test conditions shown in part (a) of AC Test Loads. Transition is measured ± 200 mV from steady-state
voltage.
17. At any given voltage and temperature, t
is less than t
and t
is less than t
to eliminate bus contention between SRAMs when sharing the same
data bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed
to achieve High-Z prior to Low-Z under the same system conditions.
18. This parameter is sampled and not 100% tested.
