Notes:
4. 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.
5. t
HZOE
, t
HZCE
, and t
HZWE
are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured
±500
mV from steady-state voltage.
6. 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.
7. The internal write time of the memory is defined by the overlap of CE LOW, 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.
8. The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of t
