1.2 Operating Conditions
*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 extended temperature
product defined by this specification.
2. All specified voltages are with respect to GND.
Minimum DC voltage is -0.5V on input/output pins and
-0.2V on V CC and WP#/ACC pins. During transitions,
this level may undershoot to -2.0V for periods <20ns.
Maximum DC voltage on input/output pins is
V CC +0.5V which, during transitions, may overshoot to
V CC +2.0V for periods <20ns.
3. Maximum DC voltage on WP#/ACC may overshoot to
+13.0V for periods <20ns.
4. WP#/ACC erase/program voltage is normally 2.7V-
3.6V. Applying 11.7V-12.3V to WP#/ACC during
erase/program can be done for a maximum of 1,000
cycles on each block. WP#/ACC may be connected to
11.7V-12.3V for a total of 80 hours maximum.
5. Output shorted for no more than one second. No more
than one output shorted at a time.

NOTES:
1. See DC Characteristics tables for voltage range-specific specification.
2. Applying WP#/ACC=11.7V-12.3V during a erase or program can be done for a maximum of 1,000 cycles on each block.
A permanent connection to WP#/ACC=11.7V-12.3V is not allowed and can cause damage to the device.
