*WARNING: Stressing the device beyond the "Absolute Maximum Ratings" may cause permanent damage. These are stress
ratings only. Operation beyond the "Operating Conditions" is not recommended and extended exposure beyond the "Operating
Conditions" may affect device reliability.
Notes:
1. The operating temperature is for extended temperature product defined by this specification.
2. All specified voltages are with respect to VSS. Minimum DC voltage is -0.5V on input/output pins and -0.2V on VDD and VPP
pins. During transitions, this level may undershoot to -2.0V for periods <20 nS. Maximum DC voltage on input/output pins are
VDD +0.5V which, during transitions, may overshoot to VDD +2.0V for periods <20 nS.
3. Maximum DC voltage on VPP may overshoot to +13.0V for periods <20 nS. Applying 12V ±0.3V to VPP during erase/write can
only be done for a maximum of 1000 cycles on each block. VPP may be connected to 12V ±0.3V for a total of 80 hours
maximum.
4. Output shorted for no more than one second. No more than one output shorted at a time.
