NOTES:
1. The ICC current listed includes both the DC operating current and the frequency dependent component (@ 5 MHz).
The frequency component typically is less than 2mA/MHz, with OE# at VIH.
2. ICC active while Embedded Algorithm (program or erase) is in progress.
3. DC test conditions: VIL = 0.3V, VIH = VCC - 0.3V
