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.

DC test conditions: VIL = 0.3V, VIH = VCC - 0.3V
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.
