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 7. 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 OE#, RESET#, and
WP#/ACC is –0.5 V. During voltage transitions, OE#,
WP#/ACC, and RESET# may overshoot V
SS
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
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.
