Operating ranges define those limits between which the func-  
tionality of the device is guaranteed.  
Notes:  
1. Minimum DC voltage on input or I/O pins is 0.5 V.  
During voltage transitions, input or I/O pins may  
overshoot VSS to 2.0 V for periods of up to 20 ns.  
Maximum DC voltage on input or I/O pins is VCC +0.5 V.  
See Figure 7. During voltage transitions, input or I/O pins  
may overshoot to VCC +2.0 V for periods up to 20 ns. See  
Figure 8.  
2. Minimum DC input voltage on pins OE#, RESET#, and  
WP#/ACC is 0.5 V. During voltage transitions, OE#,  
WP#/ACC, and RESET# may overshoot VSS to 2.0 V  
for periods of up to 20 ns. See Figure 7. Maximum DC  
input voltage on pin RESET# is +12.5 V which may  
overshoot to +14.0 V for periods up to 20 ns. Maximum  
DC input voltage on WP#/ACC is +9.5 V which may  
overshoot to +12.0 V for periods up to 20 ns.  
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  
Ratingsmay 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 device reliability.
