Notes
1) For test conditions, see “AC test conditions”, Figures A, B, and C
2) This parameter measured with output load condition in Figure C.
3) This parameter is sampled, but not 100% tested.
4) t

at any given temperature and voltage.
5) t
CH
is measured high above V

, and t
CL
is measured low below V

6) 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 with stable logic levels for all rising edges of CLK when chip is enabled.
