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.
Maximum DC voltage on input or I/O pins is V_CC +0.5 V.
See Figure 9. During voltage transitions, input or I/O pins
may overshoot to V_CC +2.0 V for periods up to 20 ns. See
Figure 10.
2. Minimum DC input voltage on pins A9, OE#, RESET#,
and WP#/ACC is –0.5 V. During voltage transitions, A9,
OE#, WP#/ACC, and RESET# may overshoot V_SS to
–2.0 V for periods of up to 20 ns. See Figure 9. Maximum
DC input voltage on pin A9 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 +12.6 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
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.
