The specified value applies with the outputs 4. This parameter guaranteed but not tested. 5. Test conditions as specified with output loading as shown in Fig. 1 unless otherwise noted. 6. tHZCS, tHZOE and tHZWE are specified with CL= 5pF as in Fig. 2. Transition is measured +/- 200 mV typical from steady state voltage, allowing for actual tester RC time constant.
7. At any given temperature and voltage condition, tHZCS, is less than tLZCS, and tHZWE is less than tLZWE. 8. WE\ is HIGH for READ cycle. 9. Device is continuously selected. Chip selects and output enable are held in their active state. 10. Address valid prior to or coincident with latest occurring chip enable. 11. tRC= READ cycle time. 12. Chip enable (CS\) and write enable (WE\) can initiate and terminate a WRITE cycle. 13. ICC is for 32 bit mode.
