Notes

6. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified

I

OL

/I

OH

and 30-pF load capacitance.

7. t

POWER

gives the minimum amount of time that the power supply should be at typical V

CC

values until the first memory access can be performed.

8. t

HZOE

, t

HZCE

, and t

HZWE

are specified with a load capacitance of 5 pF as in part (c) of

“AC Test Loads and Waveforms

[5]

” on page 4

. Transition is measured when the outputs

enter a high impedance state.

9. At any given temperature and voltage condition, t

HZCE

is less than t

LZCE

, t

HZOE

is less than t

LZOE

, and t

HZWE

is less than t

LZWE

for any given device.

10. This parameter is guaranteed by design and is not tested.
11. The internal write time of the memory is defined by the overlap of CE and WE LOW. CE and WE must be LOW to initiate a write, and the transition of either of these signals

can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write.
