Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During
2. Minimum DC input voltage on A9 pin is –0.5 V. During
3. No more than one output shorted to ground at a time.
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 op-
erational sections of this specification is not implied. Expo-
sure of the device to absolute maximum rating conditions for
extended periods may affect device reliability.
