*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. Operating temperature is for commercial temperature product defined by this specification.
2. All specified voltages are with respect to V_SS. Minimum DC voltage is -0.5V on input/output pins and -0.2V on V_DD and V_PP
pins. During transitions, this level may undershoot to -2.0V for periods <20 nS. Maximum DC voltage on input/output pins and
V_DD is V_DD +0.5V which, during transitions, may overshoot to V_DD +2.0V for periods <20 nS.
3. Maximum DC voltage on V_PP and #RESET may overshoot to +14.0V for periods <20 nS.
4. Output shorted for no more than one second. No more than one output shorted at a time.
