Notes:  
1. Minimum DC voltage on input or I/O pins is –0.ꢀ V. During  
voltage transitions, input or I/O pins may overshoot VSS to  
–2.0 V for periods of up to 20 ns. See Figure 6. Maximum  
DC voltage on input or I/O pins is VCC +0.ꢀ V. During  
voltage transitions, input or I/O pins may overshoot to VCC  
+2.0 V for periods up to 20 ns. See Figure 7.

3. No more than one output may be shorted to ground at a  
time. Duration of the short circuit should not be greater  
than one second.  
Stresses above those listed under “Absolute Maximum  
Ratings” may cause permanent damage to the device. This is  
a stress rating only; functional operation of the device at  
these or any other conditions above those indicated in the  
operational sections of this data sheet is not implied.  
Exposure of the device to absolute maximum rating  
conditions for extended periods may affect dce reliability.
