ABSOLUTE MAXIMUM RATINGS (1)
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
