For test conditions, see “AC test conditions”, Figures A, B, and C.
This parameter is measured with output load condition in Figure C.
This parameter is sampled but not 100% tested.
t
HZOE
is less than t
LZOE
, and t
HZC
is less than t
LZC
at any given temperature and voltage.
t
CH
is measured as high if above VIH, and t
CL
is measured as low if below VIL.
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.
Write refers to
