Notes:

1. Minimum DC voltage on input or I/O pin is –0.5 V. During voltage transitions, inputs may overshoot VSS to –2.0 V for periods of up to 20 ns. See Figure 5. Maximum DC voltage on input and I/O pins is VCC + 0.5 V. During voltage transitions, input and I/O pins may overshoot to VCC + 2.0 V for periods up to 20 ns. See Figure 6.

2. Minimum DC input voltage on A9 pin is –0.5V. During voltage transitions, A9 pins may overshoot VSS to –2.0 V for periods of up to 20 ns. See Figure 5. Maximum DC input voltage on A9 is +12.5 V which may overshoot to 14.0 V for periods up to 20 ns.

3. No more than one output shorted 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 specification is not implied. Exposure of the device to absolute maximum rating conditions for extended periods may affect device reliability.
