NOTES:
1. Stresses above the absolute maximum rating may cause permanent
damage to the device. Extended operation at the maximum levels may
degrade performance and affect reliability.
2. Minimum DC voltage on input or I/O pins is -0.5V. During voltage
transitions, inputs may overshoot Vss to -2.0 V for periods of up to
20ns. Maximum DC voltage on output and I/O pins is Vcc + 0.5V.
During voltage transitions, outputs may overshoot to Vcc + 2.0 V for
periods of up to 20ns.
3. Minimum DC input voltage on A9 pin is -0.5V. During voltage
transitions, A9 may overshoot Vss to -2V for periods of up to 20ns.
Maximum DC input voltage on A9 is +13.5V which may overshoot to
14.0 V for periods up to 20ns.

NOTES:
1. The ICC current listed includes both the DC operating current and the frequency dependent component (at 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
