Table 7. Read and Standby Modes AC Characteristics

Note: 1. The maximum value of this timing is applicable if E1 is kept Low with addresses unchanged.If needed by the system operation,

please contact your local ST representative for relaxation of the 1000ns limitation.

3. These parameters are measured according to the conditions on input and output timing reference voltage shown on Figure 6., AC

Measurement I/O Waveform.

4. The output load capacitance is 5pF without any other load.

5. These timings are given for E1 Low.

8. All timings are measured according to the conditions for output transition timing reference voltage shown on Figure 6., AC Mea-

surement I/O Waveform.
