Table 6.
Write Operation Status
Notes:
1.
DQ5 switches to
1
when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits.
See
DQ5: Exceeded Timing Limits on page 21
for more information.
2.
DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further
details.

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 V
SS
to –2.0
V for periods of up to 20 ns. See Figure 7. Maximum DC voltage on input or I/O pins is V
CC
+ 0.5 V. During voltage
transitions, input or I/O pins may overshoot to V
CC
+ 2.0 V for periods up to 20 ns. See Figure 8.
2.
Minimum DC input voltage on pins A9, OE#, and RESET# is –0.5 V. During voltage transitions, A9, OE#, and RESET# may
overshoot V
SS
to –2.0 V for periods of up to 20 ns. See. Maximum DC input voltage on pin A9 is + 11.0 V which may
overshoot to 12.5 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 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 device reliability.
