Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V.
During vo lta ge transitions , in put or I/O pin s may
overshoot V
SS to – 2.0 V for pe riods 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
2. Minimum DC input voltage on pins A9, OE#, ACC, and
RESET# is –0.5 V. During voltage transitions, A9, OE#,
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 A9, OE#, ACC, and RESET# is +12.5 V
which may overshoot to +14.0 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.
Expo sure o f the device to absolute maximum rating
conditions for extended periods may affect device reliability.
