Notes:
10. AC characteristics (except High-Z) for all 8-ns and 10-ns parts are tested using the load conditions shown in Figure (a). All other speeds are tested using the
Thevenin load shown in Figure (b). High-Z characteristics are tested for all speeds using the test load shown in Figure (d).
11. Device is continuously selected. OE, CE, BHE and/or BHE = VIL.
12. WE is HIGH for Read cycle.
13. Address valid prior to or coincident with CE transition LOW.
