Notes:
11. Unless otherwise noted, test conditions assume signal transition time of 2 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output
loading shown in (a) of AC Test Loads.
12.
tCHZ, tCLZ, tEOV, tEOLZ, and tEOHZ are specified with A/C test conditions shown in part (a) of AC Test Loads. Transition is measured ± 200 mV from steady-state
voltage.
13. At any given voltage and temperature, tEOHZ is less than tEOLZ and tCHZ is less than tCLZ 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.
14. This parameter is sampled and not 100% tested.
