NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUMRATINGS 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 maximumrating
conditions for extended periods may affect reliability. No termnal voltage may exceed
Vcc by +0.5V unless otherwise noted.
2. Inputs and Vcc termnals only.
3. Output and I/O termnals only.
