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. No terminal voltage
may exceed VCC by +0.5V unless otherwise noted.
2. Inputs and VCC terminals.
3. Outputs and I/O terminals.
