Notes:
1. ICC is dependent on output loading when the device output is selected. Specified ICC(max.) is measured with the output
open.
2. ICC is dependent upon the number of address transitions specified ICC(max.) is measured with a maximum of one
transition per address cycle in random Read/Write and EDO Fast Page Mode.
3. Specified VIL(min.) is steady state operation. During transitions VIL(min.) may undershoot to –0.9V for a period not to
exceed 10ns. All AC parameters are measured with VIL(min.)≥VSS and VIH(max.)≤VCC.
4. Specified VIH(max.) is steady state operation . During transitions VIH(max.) may overshoot to VCC+0.9V for a period not
to exceed 10ns. All AC parameters are measured with VIL(min.) ≥ VSS and VIH(max.) ≤ VCC .
