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
to –2.0 V for periods of up to 20 ns. See Figure 1. Maximum DC voltage on input or I/O pins is V +0.5 V.

2. Minimum DC input voltage on pins A9 is -0.5 V. During voltage transitions, A9 may overshoot V to –2.0 V for
SS
periods of up to 20 ns. See Figure 1. Maximum DC input voltage on pin A9 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. Exposure of the device to absolute maximum rating conditions for
extended periods may affect device reliability.
