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 con-
ditions for extended periods may affect reliability. No terminal voltage may
exceed VCC by +0.5V unless otherwise noted.
2. Input and VCC terminals only.
3. Outputs and I/O terminals only.
