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 –1V for a period not to exceed 15ns. 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+1V for a period not to exceed 15ns. All AC
parameters are measured with VIL(min.) ≥ VSS and VIH(max.) ≤ VCC .
