This parameter measured with output load condition in Figure C.
This parameter is sampled, but not 100% tested.
t
HZOE

at any given temperature and voltage.
tCH measured as high above V
IH
, and tCL measured as low below V
IL
.
This is a synchronous device. All addresses must meet the specified setup and hold times for all rising edges of CLK. All other synchronous inputs must
meet the setup and hold times for all rising edges of CLK when chip is enabled.
