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 2 mA/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

NOTES:
VZ is programmable from -2V to +7V. IOL & IOH programmable from 0 to 16mA. Tester Impedance Z0 = 75 Ω.
VZ is typically the midpoint of VOH and VOL.
IOL & IOH are adjusted to simulate a typical resistive load circuit. ATE tester includes jig capacitance.
