NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device.
This is a
stress rating only and 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 to absolute maximum
rating conditions for extended periods may affect reliability.
2. VCC terminals.
3. All terminals except VCC.
