Notes
1. Minimum DC voltage on input or I/Os is –0.5 V. During voltage transitions, inputs or I/Os may undershoot V
SS
to –2.0 V for periods of up
to 20 ns. See
Maximum DC voltage on input or I/Os is V
CC
+ 0.5 V. During voltage transitions inputs or I/Os may overshoot to
V
CC
+ 2.0 V for periods up to 20 ns. See
2. Minimum DC input voltage on pins A9 and ACC is -0.5V. During voltage transitions, A9 and ACC may overshoot V
SS
to –2.0 V for periods
of up to 20 ns. See
Maximum DC voltage on pins A9 and ACC 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.
4. 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.
