REV OR
12. Transition is measured ±200mV from steady state voltage prior to
change with specified loading in Figure 1. This parameter is
sampled and not 100% tested.
Notes:
9.
CE
and
WE
must be LOW for WRITE cycle.
10. If
CE
goes HIGH simultaneously with
WE
HIGH, the output remains
in a high impedance state.
11. Write Cycle Time is measured from the last valid address to the first
transition address.
